Electrolysis of water and salt, 9v battery, 2 screws and an elastic

“Can you take a water molecule apart?” the children asked. “Yes you can, but you have to use¬†Electrolysis”, my husbond said.

The talk came from talking about, how much Hydrogen there is in the universe. Actually 73% of the universe consists of Hydrogen and the children wondered why it doesn’t explode.

They also wondered why water puts out fire, when it contains that flammable Hydrogen.

So we decided to try separating hydrogen and oxygen from water through Electrolysis.

Hydrogen is released by the minus pole, also called the cathode.
Oxygen (oxygen) is released at the plus pole, also called the anode.
