  • If you try inhaling the "hydrogen gas" you will first feel extreme pain for 2 seconds then die. I dont think just plain hydrogen gas will do that.

  • can you collect the copper from the solution to use to plate something?

  • @8DuncanConstruction8 In this experiment I dissolved the zinc and not the copper.

  • I am superman. : )

  • Isn't it Hydrogen Gas that is produced, and not Chlorine Gas? I see Zinc Chloride in the equation, but isn't that a liquid?

  • Why did you just retrieve the penny with your bare fingers. No type of protection.

    You said "Hydrocloric Acid is dangerous and can burn your skin".

    Epic Fail.

  • I IST A MONSTER >:D

  • Whoops.... :P
