The document describes an experiment to synthesize water from its constituent elements, hydrogen and oxygen. Hydrogen is produced by reacting magnesium and hydrochloric acid. Oxygen is produced by reacting hydrogen peroxide with yeast. The gases are collected in syringes and mixed through a tube. If the mixed gases explode when ignited, water has been successfully synthesized from hydrogen and oxygen.

3. Procedures ALWAYS PROTECT YOURSELF BY WEARING SAFETY GLASSESNote: HCl is a highly corrosive acid. If the chemical spills on you, flush with water immediately. Grab the two ring stands and place them on the counter top. Use the two clamps to adjust them on the ring stands. Proceed by sealing one of the 30 ml beakers with a rubber stopper. Check around the edges of the beaker to make sure no leakage is possible. Weigh approximately 0.150-0.180 g of yeast in a balance weight using a paperweight. Do not forget to tare the balance weight. Using the paperweight, transfer the yeast into one of the openings of the rubber stopper.

4. Procedures (Cont’d) Close off the beaker with two stopcocks. Make sure they are inserted properly. Fill 5 ml of the 6 ml syringe with HOOH Attach the syringe with HOOH in one of the stopcocks. In the other stopcock, place an empty 12 ml syringe. Have both stopcocks opened. Slowly add the HOOH into the beaker. You will see the empty syringe fill with up with air. Once all the HOOH has been emptied, quickly close the stopcock and attach another 12 ml syringe. When the former syringe fills with air, close the stopcock and open the valve of the empty syringe. After the second 12 ml syringe fills: close the stopcock, add one of the 20 ml syringes, and use it to collect oxygen gas. NOTE: Because the beaker held about 15 ml of air, the air had to be displaced when the reaction occurred. This ensures the final gas held inside the last syringe is only oxygen. 9. Once the oxygen gas is collected, put it aside.

5. Procedures (Cont’d) Follow instructions 2-8, using HCl and Mg, to collect Hydrogen. When both gases have been compiled, connect the syringes with the plastic tube. Mix the gases by pushing the plungers back and forth. Both syringes contain hydrogen and oxygen gas. If you wish to make sure the syringes contain pure oxygen and hydrogen, you may ignite the gases using soap and water. If it explodes, you have created water. NOTE: make sure you have permission to go forth with the explosion.
