  1. 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?


  2. 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

  3. i have a cell battery. im using salt water in each cell and zinc and copper. i have about 15 cells and i get about 14 to 15 volts but i get no amps/current… so a small christmas light didnt light up

  4. 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 ?

  5. So being English I made a strange cell first of its type in the world yes and you and I know we have thousands of videos of battery's more than any time on earth. only one has to change the world I have a solid nylon electrolyte. how it works is the question very few can answer and may be just a few understand please help lots of it.
