today we're going to do an experiment recreate a voltaic pile which was the first electrical battery that could continuously provide an electric current to a circuit it was invented by the italian physicist alessandro volta who published his experiments in 1799 now batteries have come a long way from being too small and from simple to sophisticated practices batteries are essential to our everyday lives so today we're going to see how to make a battery [Music] now creating this voltaic file is pretty simple you only need copper zinc paper vinegar and salt first we need to make sure we have the same amount of all fundamental ingredients in this particular battery we're going to use 11 pieces 11 pieces of copper which is coins of 5 cents 11 discs of zinc and we need to cut 11 pieces of paper first we draw a circle and then the second and so on in that way we're going to have the same size of wallpaper pieces we must be very careful when we're cutting them because we don't want to make some pieces larger than the others because then we will get a short circuit and trust me we don't want that the next step is to dissolve the salt into the vinegar salt and vinegar create electrolytes which are essential to transmit the electric current but i made a mistake the cardboard i initially used was too thick for the electric current to pass from one material to the other so what i needed was a thinner paper and this is what i got i draw one circle in that i cut off a strip of paper fold it several times and cut it once [Music] now that we have all knitted pieces we're ready to start our pile so our logic is that we have copper electrolytes and then put the same disk on the other side this is one electric cell and it is measured to produce 0.64 volts now if we create a bunch of them then we should have a fair amount of voltage to power a single strip of led lights first we put down on the table a small piece of aluminum sheet to insulate the pile from the rest of the environment okay this will take forever [Music] as you can see i repeat the same steps i first put a copper disc then a paper full of electrolytes and then a zinc disk i repeat it several times so we get a fair amount of voltage because 0.64 volts doesn't produce too much power to light an led strip after we finish we will have 11 cells that will produce the same amount of electrical energy as a double leg commercial battery [Music] now that we are finished we need to get an led strip now i'm going to put the positive side of the circuit to the copper and the negative one to the zinc disk we need to make sure that the paper discs are soaked enough to carry enough electrolytes but not drip water through cells because then our butter will show sugar eventually and this is the moment of truth a spark and that was it you see i might have spending too much time creating the pile and the paper disks got dry this means that not enough electrolytes were transferring from one side to the other of the pile and the energy went down immediately made the paper this sweat again and this was the result we were able to create light from sink copper and soaked paper which is awesome you see i wasn't sure whether this experiment would work but thankfully it did [Music] [Music] the power is not comparable to that of a 9-volt battery and even if you have a well-soaked paper it soon will die out by the way if you don't have any vinegar at home then salt water will do as well the battery lasted for 4 minutes and 37 seconds and you can have great fun doing that by yourself at home you see recreating the voltaic pile is perfectly safe the voltage is very low to affect the human body and you can increase the battery life by adding more cells how did you like this video let us know down in the comment section and if you have your own experience recreating the voltaic pile please let us know until then see you next time goodbye
