    I love the white socks approach and the fancy pencil sharpener ;-D

    I always turn the carbon rod before pulling it, to break any adhesions. Makes pulling a full rod much easier.

    isn't there Acid in that battery?
    do you want to be handling that bare Hands?

    No need for a hammer, just use your pliers around the case a couple times and the rods will come right out.

    I don't understand why you are using a stationary camera for recording, it's much nicer when we, as viewers, feel like we are inside of a washing machine xD

    Dollar Tree batteries (the red and silver ones) have carbon rods in the center, and it's one $1 for a pack of 3 D cells :D

    Reaction:
    Zn(s) + 2MnO2(s) + 2NH4+(aq) → Mn2O3(s) + Zn(NH3)2 2+(aq) + H2O(l)
    Zinc gives up electrons to manganese dioxide, in essence. :D

    Video proves that talkative people bla bla bla can still post videos. Man just bust the battery and get the rods..no wonder you have no friends..too much talk.
