  • 6:15-:35 --> typo "...endothermic reaction..." should say "a solid to a liquid"

  • I LOVE black fingernails....

  • ohhhhhhh..

    now i get it..

    Thanx! =]

  • The reason was because it required energy to go from a solid to a liquid just like when you heat ice it melts. Since energy was removed from the surroundings to become liquid the temperature of the surroundings decreased.

  • good video!

    But, i have one question

    why did the temp. go down on the last experiment?
