How to Make a Lemon Battery

Hank shows us another SciShow: Experiment! This time he’s tackling what may be the most cliche, well-known and misunderstood experiment of all time: the lemon battery. The take home message in this one is: the electricity is NOT in the lemon. Just that delicious juice.

    If you had to make an electronic device and were being followed
    worried that wireless signal jammers could sabotage your wireless remote control activation device
    then decided to build an old school analog device that ran off an alarm powered by C or D cell batteries
    could you construct a improvised battery to generate the spark?

    i saw this experiment of a small sized battery capacitor , charging it causes it to produce pressure like its being inflated it hardens up and in a serries they act together sort of prventing a sudden discharge so as it all discharges in sync .its strange science behind this. but discharges extremly slow in comparisen to chargeing .a fantasy science projectno less

    okay, hold on a second, every video I see about this topic gives different explanations to what the heck is going on.. so let me ask, is this science accurate and if so, why have 10% of viewers disliked the video ?

    How does this work without a separator? And since it does, then why is a separator used in batteries?
