Do you know how to separate water?
To be honest, I didn’t even know it was possible.
Sure, I knew that water was H2O. I even knew that was two parts hydrogen to one part oxygen.
I just had no idea you could return them to their gas forms.

And, it’s not even rocket science!
Fortunately, though, we have one. A rocket scientist, that is. Yes, hubby really is a rocket scientist.
So, when it comes to chemistry (or any of the physical or life sciences) I step aside and let the expert take over.
We even invited another homeschool family to join us.
I did, what I do best. I sat up in the kitchen with the other mom and enjoyed a perfect latte, while hubby and the teens headed down to his lab (a table set out on the deck) for a few chemistry experiments.
We went and had a peek while they were learning how to separate water.
Here is my interpretation of the scientific explanation provided by hubby. I am no rocket scientist, so for the most part I used simple words.
Step by Step: How To Separate Water
- Fill a beaker with water.
- Add an electrolyte (small amount of sulfuric acid or sodium carbonate).
- Bend two lengths of stainless steel wire. When the experiment runs, each wire will have one end in an inverted test tube inside the beaker and the other over the side of the beaker holding the tube in place. (Visualize a sideways S with one end in the tube, then bending up along the side, turning and going out along and down the side of the beaker). Once in the proper shape, put them aside. If possible, have a sleeve over the wire in all parts which will be outside of the test tube.
- Fill each tube with water and using a finger to cover the top of the tubes, invert them and immerse it in the water.
- Add the wires with one end in the tube, the other end outside of the beaker.
- Wire up a DC power source between 4 and 20 volts (battery) to the wires: positive to one, negative to the other.
- Turn on the power and watch the bubbles – the hydrogen will collect on the negative side, oxygen on the positive side. Remember, there should be about 2 times the amount of hydrogen.
