Where to dispose of used batteries: making unusual crafts

Battery device

The battery is a simple, cheap and reliable source of energy for household appliances.

Battery design.

Inside such a device are:

1. Positively and negatively charged poles.
2. Catholyte.
3. Mercury, nickel, lead, cadmium, nickel.
4. Resin.
5. Carbon rod.

The most important indicator of a power source is the charge capacity. It determines the price and operating period: the larger the capacity, the longer the battery will last.

How to check your phone battery

For the test, you need a device called a voltmeter, which helps measure the voltage of the equipment. It is recommended to first perform a visual inspection of the battery. If the battery was in operation for a long time, then its structure could be subject to deformation, for example, swell. If liquid gets on the contacts, it will oxidize. These factors affect the battery capacity and reduce the specific value. To check the battery you need:

• remove the battery from the device;
• attach the positive contact of the voltmeter to the positive pole;
• do the same with the negative;
• in the settings, set the nominal value of the measured voltage.

The voltage that you received during measurement will display the state of charge of the battery. To evaluate the indicator, you can use the following values:

• less than 1 V – the battery needs to be charged;
• about 2 V – the battery is charged, the capacity is average;
• 3.6-3.7 V – fully charged battery with high capacity.

How to determine if the battery is charged

Many companies put a scale on the shell of their product that displays the amount of charge. When the light is red, it means the battery needs to be replaced.

Many companies put a charge scale on the shell of their product.

If there is no indicator, you can determine the amount of charge as follows: lift the battery 3-4 cm from the table (or other flat surface) and carefully release it. A discharged battery will bounce and fall, but a charged one will land smoothly.

How to make an electromagnet with your own hands?

A small magnet can be created even at home if you have a rechargeable battery with a low charge level. It will help to study the action of electromagnetic forces in practice.

Take batteries, 1.5 meter copper wire wrapped in insulating material, and a nail. The wire is wound onto the nail over its entire surface. A few centimeters of wire are left along the edges to attach them to the battery.

The magnet will only attract small and light objects.

By disconnecting the ends, the magnet loses its attractive force.

Disposal rules

Many packages indicate that batteries should not be thrown away - only recycled. There are enough harmful compounds inside the battery to cause irreparable damage to soil, water and air. The contents of food sources are also toxic for our health, so we must follow the rules for their disposal.

In some areas of the country it is difficult to find special collection points for waste energy sources.

In this case, proceed as follows:

1. Agree with friends and family that you or someone else will be responsible for collecting and disposing of dead batteries.
2. Find collection points in your nearest locality. Every large city has at least one battery collection point. Most often they are located next to hardware or furniture stores.
3. If you live in a populated area far from the metropolis, you can negotiate with the local Ministry of Emergency Situations or representatives of factories that recycle batteries.

Never leave old batteries in the public domain. Store them in plastic boxes until disposal. Don't forget: Toxins seep into the air you and your loved ones breathe.

What can be done from used batteries

A discharged power source can be charged for a short time if purchasing a new one is not possible at the moment. To do this, carefully deform the body, preventing it from being damaged. If the shell is cracked, then the battery can no longer be placed in the electronics, since caustic liquid will leak out of it and ruin the device.

From a battery that has served its intended purpose, you can make a lamp, designing it according to your own wishes.

Take a small light bulb for crafts so that the remaining battery power is enough to produce a glow

To make sure that the battery is discharged, it is thrown onto the table with the minus side down from a height of three centimeters. A new battery falls with a dull sound, a dead battery falls loudly and bounces off.

To make it you will need:

• used but not damaged battery;
• bulb;
• thin copper wire;
• scotch;
• paper and clay for creativity.

Manufacturing instructions:

1. The wire is divided into two parts.
2. Tape one part of the wire to the terminal with a negative charge.
3. The second part is wound around the metal area of ​​the lamp.
4. The free end of the wire (the one on the lamp) is attached to the second terminal of the battery.
5. In order for the lamp to light up, the circuit must be closed.

The light from the lamp is quite bright.

You can turn the product into an interesting craft by covering the battery with cardboard or plasticine. The resulting flashlight can become a lighting fixture in a dollhouse or become a bug with antennae terminals. Play with the product under adult supervision.

Similarly, you can highlight the glass.

Precautionary measures

Do not dispose of it yourself. Do not burn or bury batteries, no matter how many. According to the latest data, one old battery harms the territory that can be inhabited by a hedgehog, 2 trees and a thousand worms.

Do not store batteries in metal boxes. The contents cause metal corrosion and seep into the soil and groundwater.

Failure to recycle causes irreparable damage to the environment and public health. Recycling old batteries is an event organized solely for the purpose of preserving the environment.

Battery in a beer can

Crafts from old things
To create a battery with your own hands in a beer can, you need to take:

• aluminum can;
• coal from a fire in the form of crumbs or dust;
• paraffin candle;
• graphite rod;
• salt and water;
• foam more than 1 cm thick.

First you need to cut off the top of the can. Then make a circle out of foam plastic that fits the bottom of the jar. It is necessary to make a non-through hole in the circle for the rod. Place polystyrene foam at the bottom of the jar and stick graphite into it

It is important that the rod is positioned exactly in the center of the jar. The space around the graphite rod must be filled with coal

Then all that remains is to make a saline solution using 0.5 liters of water and 3 tbsp. spoons of table salt. Stir the solution until the crystals dissolve, it is better to do this in warm water. Pour electrolyte into a jar and seal it with wax

It is important that the graphite rod looks outside the can

Connect the wires to the graphite rod (cathode, plus), and the body of the aluminum can (anode, minus). In order to obtain a voltage of 3 Volts, you must connect at least 2 cans in series. The resulting battery can power a light bulb, calculator and watch. They can also be recharged.

Types and markings of batteries

The classification is based on the materials from which the battery components are made:

1. Lithium. The basis of the cathode is lithium metal.
2. Mercury. Zinc serves as the anode, and mercury oxide serves as the cathode.
3. Alkaline (alkaline). The electrolyte contains potassium hydroxide alkali, the electrodes are made of zinc and manganese dioxide.
4. Silver. The cathode is based on silver oxide, the anode is made of zinc.
5. Saline. An ammonium chloride solution is used as an electrolyte, which is a salt bridge between zinc and manganese oxide electrodes.

In the production of batteries, special markings are used that indicate the parameters and type:

• lithium - CR;
• alkaline - LR;
• silver - SR;
• saline - R.

In addition to the above classification, batteries differ in voltage, height and diameter.

In everyday life, batteries have their own names:

• AA - “finger”;
• C - “thumbelina”;
• D - “barrel”;
• AAA - “little finger”;
• flat - “tablet”.

Little tricks

• Small half-liter bottles are easier to manipulate, and larger ones produce more spectacular swirls.

• The water can be colored a little. And even add glitter to it!

• If you want your child to also get practical benefits from your activities, tell him how to behave on a river or in the sea if he gets caught in a whirlpool. The strength of the whirlpool weakens at depth, so swimmers who feel like they are being pulled into a funnel are advised not to waste energy fighting the current, but to allow it to pull them in. Having dived into the funnel, you need to make several strong strokes underwater and then, most likely, you will be able to emerge far from the danger zone. But the best thing, of course, is never to get into such a situation!

Good luck with your experiments! To be continued.

If you conduct experiments at home yourself, write to us, send photos and videos of your experiments. Let's put together a home laboratory workshop!

Flower tree and topiary with roses

It is a classic topiary. A pot, a thin trunk, a lush crown of delicate flowers made from napkins. This DIY topiary is a little more complicated because you will need to secure a thin stem in the pot. Plaster is used for fixation. Set of materials:

1. Flower pot.
2. Multi-colored napkins.
3. Chinese chopsticks tied into a bundle of sufficient thickness.
4. Threads.
5. Newspapers for the base of the crown.
6. Stapler, scissors, glue.

What else can you make flowers that decorate the crown from? Paper is a plastic material, but short-lived. Flowers can be made from satin ribbons or textiles cut into strips.

For such a topiary you need the following materials:

1. Ribbon and matching threads. The ribbons are rolled up in the shape of roses and secured with threads.
2. Needle.
3. Decorative ball as a base.
4. A cache-pot or pot, a straight dry branch for the stem.
5. Beads matching color.
6. Glue (it is better to take transparent Moment), scissors, a candle (for processing the edges of the tape so that they do not crumble).

Description of the experience

The water funnel is an amazing sight, reminiscent of a tornado - with a long flexible “proboscis”, writhing and swaying like a living creature.

“To get a spectacular whirlpool in miniature, the water needs a little help - spin, stir the water, give the flow additional centrifugal force.

This is not difficult to do if you build something like an hourglass from available materials.

You will need

• Two identical plastic bottles
• Glue that securely holds plastic together
• Scotch
• And water, of course!

So, first you need to drill fairly wide holes in the bottle caps. Then the covers are glued to one another with the outer sides. For reliability, they can be additionally wrapped with tape on the outside.

Now we pour water into one of the bottles, screw a structure of two caps on top and screw the empty bottle into it.

We quickly turn our structure over (make sure the plugs are tightly screwed in!) and make several quick circular movements, as if stirring tea in a glass with a spoon.

Reply to the post “Purposefulness is the key to unprecedented sensations”

Ha! Reminds me. The 90s in one small but proud republic. Work as an assistant driver on the shunting TEM-2. We haven’t seen a salary for 8 months, inflation is crazy. Pushing cars on the factory tracks. There is a gas pipeline with “raw” gasoline running next to us. Every 15-20 meters a hole is drilled and a wooden cap is hammered. They sneak up with canisters and barrels, attach hoses and fill the containers. We still need to avoid getting caught by security. Well, I decided to take part. He sat down on the pipe, prepared the hose, and pulled out the plug. The gasoline is gone. I didn’t expect such pressure and therefore I was covered in gasoline from the waist down, and it was also hot. At first I felt discomfort in the groin, then it began to burn, and then it began to BURN. How painful it is! I jumped into the locomotive and grabbed a bottle of water. And he made another mistake - he didn’t pay attention to why the driver was shouting, through laughter, “don’t touch the water. ". Whatever it is, don’t touch it - he opened the bottle and directed a stream of water onto his personal belongings in anticipation of relief. No matter how it is. I felt like I had been scalded by boiling water, and then I started screaming. - “Blow some air!” How can I do this?! The hope is that the driver will take pity and blow on my balls - I understand from him that he won’t, he can’t breathe from laughing. The only way left. We accelerated the Lokomotiv to 40 km/h, it couldn’t go faster, and I hung my bells out the window, hiding my face from surprised glances. I still don’t know what kind of reaction this is between raw gasoline and water.

Why shouldn't you throw batteries in the trash?

A small battery contains a huge amount of dangerous elements.

Once in a landfill, it begins to lose the integrity of its body and release its toxic filling into:

• soil,
• The groundwater,
• atmosphere.

These toxic elements, together with food and drink, enter the human body. It is in this form that the discarded battery comes back to us from the landfill.

The batteries contain:

1. Lead. A toxic substance that negatively affects the development of the brain and nervous system, especially in young children. When accumulated in the human body, it can cause coma, convulsions and even death. There is no level of lead exposure considered safe.
2. Mercury - dangerous fumes of this substance threaten tuberculosis, affect the liver and gallbladder, and disrupt the functioning of the nervous system. Children and women are most vulnerable to mercury poisoning.
3. Cadmium is a toxic substance that causes lung cancer and also negatively affects kidney function. Cadmium remains in the liver and kidneys and is excreted extremely slowly from the body. Nickel-cadmium batteries are very dangerous items. Care must be taken to ensure that children do not play with such items.
4. Nickel. Intoxication leads to disruption of the heart.
5. Zinc. May cause acute intestinal infections.

Environmental contamination has been occurring for a whole century, and it is impossible to stop this process. However, this can be prevented if used batteries are promptly returned for recycling.

Extinguishing alcohol with water

In response to the comments, Light it up to the fullest!

Old people remember commercials for toothpaste, where one part is treated with toothpaste, the other is not...

Inspired by this advertisement, I decided to make a soft egg. Vinegar in a glass, egg in a glass. We wait from 4 to 6 hours.

And here is the result. The egg is raw!

Sorry about the video format, I'll have to stretch my neck

In the end, I finished playing and it burst when it fell on the floor. But the experiment is interesting, to show the children the best!)

Crafts from plastic bottles

Plastic bottles are one of the most common types of environmentally hazardous waste. Now on the Internet you can find many examples of the secondary use of this container.

Ladybug from a bottle

You can make funny ladybugs from plastic bottles to decorate your flower bed.

To complete the work you need to prepare:

• plastic bottle with stopper,
• acrylic paints and brush,
• disposable fork,
• knife,
• candle.

Step-by-step master class.

1. You need to cut off the bottom of the bottle with a knife, paint it on both sides with bright paint and let it dry.
2. Heat the teeth of a plastic fork over a candle flame, bend and cut. This is a blank for the antennae.
3. Make a head from a bottle cap. Paint it black, dry it, and glue on the mustache.
4. Draw or glue eyes from paper.
5. Draw black spots on the back.
6. Glue the cork head to the body of the craft.

The product is ready. If desired, you can make a whole family of such insects from bottles of different capacities.

Mushrooms for the garden based on a plastic bottle

Original garden figurines perfectly decorate a summer cottage and look original in a flowerbed and walking area of ​​a kindergarten.

You can make mushrooms with your own hands from waste material at minimal cost to decorate the area near your house.

To work you need to prepare:

• a thick plastic bottle of milk or automotive chemicals,
• an old pan roof,
• cement, acrylic paint.

The work ahead is simple.

1. The base of the craft will be the bottle. It is the stem of a mushroom.
2. Work begins by attaching the cap to the bottle. This is the base of the mushroom cap. It can be secured by fixing the handle in the neck of the bottle with a mechanical connection. Or using a fabric-based patch. Scotch tape is no good.
3. A solution is prepared from cement.
4. Carefully coat the bottle and cap with the solution. The work is carried out in several stages. After the cement layer has dried, the next one is carefully applied.
5. When the product takes the shape of a mushroom, it is dried.
6. The stem and cap are covered with paint. The brown or red color for the cap is obtained by adding powdered dye to white acrylic paint.

The mushroom is ready. This garden figurine is enough for at least a season. It does not suffer so much from moisture as it is afraid of mechanical damage. A soft plastic bottle is not suitable for the base. It will sag, the cement layer will crack and fall off.

Plastic bottles are used to make containers for flowers, jars for pencils and storage of various small items, funnels and scoops for the garden. You can make original flower arrangements from them. Plastic can be easily painted with acrylic paint.

Large bottles and canisters are used to make various flowerpots for the home and garden, and garden figurines. The simplest example of such figures is found everywhere. These are piglets from large bottles.
