This project is very easy to do!
Needed: An aluminum can. A sheet of copper foil of 0.3-0.4mm. Two insulating rubber spacers. An engine of a cd rom 2-3 volts, to be recovered from the inside of a PC. 1 liter of water with 3-4 tablespoons of salt for foods.The duration of rotation of the motor is approximately 7-8 minutes. When the salt water loses energy, it must be filled with fresh water and salt. For the success of this experiment it is necessary to have an engine that has a low power consumption 15-20 mA max and a voltage of 2-3 volts of a motor of a cd rom inside the pc. The use of engines for toys are not suitable for this type of experiment.
* The copper foil can’t be replaced with other metals.

Janyaa 6th class science experiments video
Please tell me the theory and the other name of the project
hey can use a painted aluminium can like for example soda cans of mountain dew etc or do i have 2 scrape the paint off
Le + c'est-un cuivre
Is the 'salt water' you made accurate to ocean water? I have a theory and am ready to test it if this is.
Can I use wristbands instead of spacer rubber?And what can I use instead of copper sheet?
what is the name of rubber?
What is that yellow colour thing
Should i make it in science fair?Will it work 100%??
is the voltage depends on the area of surface of the cooper and the can? and if we continously add the salt water when there's no more electricity how long the can will last?
is the voltage depends on the amount of salt?
shall it works….?plz tell bcoz coming Friday my project day……..
Where did you get the propellor and motor
So it can be charge through the mobile phones?
remote light control

how many volts produce this cell 0,50 or 5 volts or 3volts
Nice
now put it in the ocean.
I wonder why this produces 0.5V instead of 1.66V and why it gets lower over time
LMAO…ROF… 4 years later and a commercial or residential device still not in production.
low cost but short energy
how long would this last
can i use aluminum instead of copper?
Use magnesium instead of coca cola for better results !
sweet free AC!!!!!

Does this operate based on the small slit in the folded sheet of copper foil which allows the salt water to fill the space between the exterior of the can and interior of the copper sheet?
It would be cool if you add some theory or just give a hint abt the physics and chemistry behind it .
Falso! O que aconteceu foi que ele ligou o aparelho ao cooler através dos fios, usando a água como condutora.
very good video keep up the good work
you are not a cool guy just in name
Great video! Check out my version using 10 cans in series, saltwater and vinegar. https://youtu.be/0F8cE4N42NQ
It is so Fake wasted my 4 hours and hate this experiment you are so dam fake and also wasted my efforts for my science fair.You are fake and stupid.
