  • did they even make any hydrogen in the first place

  • Yes we did :) You need the reaction to be quite slow as if it's too fast you'll boil the water. If you're trying to fill a balloon with hydrogen (which is what we were doing) then all you'll do is fill the balloon with steam - which isn't what you want.

  • ok now i understand

  • whats the point of making hydrogen? what use is there to it? it is flamable ? yes? and so is petrol i dont get it. The only fun thing there is if if you did it in a plastic bottle and put a cap on it and threw it

  • To make it really loud you need to mix the hydrogen with oxygen. That sets off car alarms.

  • where do you get pure oxygen? will just air do?

  • pure oxygen at a medical place

  • man all theses people suck at this

    the ballons i make when confined in a tube set off car alarms and deafen me for half an hour

  • Drano contains NaOH. Pure NaOH and perhaps some shred of Al which can easily be separated.

  • LIGHT IT ON FIRE DAMNIT

  • We did but I had to put the camera down :-)

  • ok, thank you

  • hey, where u get sodium hydroxide from?what shop?

  • In the UK you can get it from Homebase. Just ask for Caustic Soda. It costs about £3.

  • Ummmm.....Yeah I think you failed chemistry! Try putting the aluminum foil into a ball and throw them in, than pour liquid or powdered Drano into the bottle, now you get Hydrogen and if you want you can place a balloon over the mouth piece to catch the Hydrogen. Hydrogen gas is very flammable so be safe!

  • I have done this experiment before lots of times. You should use a much higher concentration of sodium hydroxide - yours didn't even start to react properly!

  • How fast things go depends on the sodium hydroxide you are using. In the UK we can buy it neat (or at least something like 99%) so you don't need that much.
