Eco-friendly, non-toxic, water-powered Do-It-Yourself battery made from the very scratch. That's our project for today. A little experiment shows where coins, foil from cigarette packs, and a small piece of cotton are possible component in making batteries. Easy steps and certainly we are not going a hard way finding things that required.
It was believed that battery discovered during Iranian dynasty in Mesopotamia, now Iraq. Technology out of battery greatly helped people so scientists made further research to improve it. Perhaps many began experimenting about the concept of battery. Later, during the 19th century, Alessandro Volta was recognized for developing an authentic batteries and he also has a solid explanation of how or why does such invention works.
With this investigatory report. We're going to share a simple technique for where we can produce battery. Importantly, battery that is actually made by our bare hands. Are you guys excited? If so, then gather all things that we need!
Materials for Making DIY Water-Powered Battery
It's composed of copper and aluminum foil or zinc. Proven to be more powerful and produces higher voltage when salt or salted water solution is used. You can test this right now, just make a little experiment. We're making sandwich!
- 1. Cigarette foil (found mostly inside every box of cigarette, fold it into half and make sure that aluminum portion is all placed outside).
- 2. Coin (either 10 cents or 25 cents as alternative).
- 3. Cotton balls (add few droplets of water).
- 4. Multi-Tester (set multitester to 1.5v DCV)
Procedure on Making Water Battery
- 1. Lay the foil on the table.
- 2. Place the wet cotton ball on the top of the foil.
- 3. Set the coin above the cotton ball. It's just the way we are making a sandwich and the cotton ball is the filling.
- 4. Slightly, compress all materials. Press, but avoid damaging the foil. Be sure that foil and coin should not meet together. Everything is all set up and done. You now have your own made water-powered battery.
Again, first the foil, followed by cotton ball, and last is coin.
Foil + Wet Cotton Ball + Coin = Battery
How To Check If Science Investigatory Project Has a Stored Energy
To check the newly created battery, use multimeter. Point it first on DCV not more than 5 volts but not greater than 10 volts. Suggested, I guess it's better with 1.5 volt since this battery doesn't really had that higher voltage. Place the positive needle on coin, for the negative should be with foil. If the pointer in multitester strikes or moving, it shows that battery has electrical power.
