How to make Hydrogen gas
What youll need
Flat aluminum about 1 full table spoon (a coke or beer can would also do the trick)
Caustic Soda (about 1 and 1/2 table spoons)
1/4 to 1/2 a cup of cold water
A medium size container of water to cool the bottle when it gets warm.
Tin snips or some way of cutting the aluminum.
1 or 2 balloons
What to do
Cut the aluminum into small pieces until you have about 1 table spoon. put the aluminum into the glass bottle. Then put enough caustic soda to just cover the aluminum. Next thing to do is add about 1/2 of cold water. The mix will star fizzing put the balloon on and what it grow. CAREFUL that the bottle doesnt get to hot. When it gets hot cool it in the container of water. Dont cool it down too much as it will slow the reaction down.
the balloon did not exploded very good as it was only blown up to half size
