How Do You Make Hydrogen & Oxygen Fuel?
Fossil fuels such as gasoline and coal provide a great source of heat and electricity, but they also pollute the planet with greenhouse gases. Hydrogen fuel provides comparable power to fossil fuels and has zero greenhouse gas emissions. Creating hydrogen and oxygen fuel from the electrolysis of water is a fairly simple concept that can be replicated on a small scale in your classroom. Step 1 Obtain a Hoffman apparatus from your teacher. Make sure the stoppers are closed on both ends. Fill the apparatus with distilled water. Step 2 Plug the electrical wires into the power source. Connect the negative wire to one terminal on the Hoffman apparatus and the positive to the other. Step 3 Turn on the power source. You will see bubbling at both electrodes within the apparatus. Hydrogen will be produced on the negative side and oxygen will be produced on the positive side. Step 4 Allow the electricity to flow until the desired amount is collected. To test your collected gases, place a test tub
