Can an aluminum can drink be a source of energy? Most modern models of calculators work not only on batteries, but on solar cells installed on their bodies. Such calculators also work well from the light of fluorescent lamps. But what if you try to make the world famous Pepsi drink become a source of energy for the calculator? It may be pointless from a scientific point of view, but it will surprise friends and acquaintances.
To start, let's watch the experiment video:
For this we need:
- One can of drink;
- A glass;
- Aluminum or food foil;
- Scotch tape;
- scissors;
- screwdriver;
- pliers;
- Two wires;
- Old salt battery;
- A piece of cardboard;
- wooden stick;
- And also the calculator itself.
First of all, we need to disassemble our battery and get out of it the coal rod, which is located in the very middle. From the battery, we also need a rubber gasket and a metal cap. In no case should you take apart alkaline or alkaline batteries, as this can be dangerous and they do not have a carbon rod.
A wooden stick should have a length of 45-50 mm, since we will need it in the battery compartment of the calculator.
We connect the wires on both sides of the stick and wrap it with foil for a more reliable connection.
Next, we wrap everything with tape to better fix the contacts.
The next thing we need to fix one wire on a coal rod. It is at this stage that a rubber cap and a metal cap from an old battery will help us.
To the second wire you need to rewind a piece of foil.
Insert the wand into the battery compartment, observing the polarity. The wire coming from the coal rod is positive, and the second is negative.
Pour Pepsi into the glass and lower the ends of the two wires into the liquid. Now you can safely turn on the calculator.
