How to Make Hydrogen With Baking Soda & Water
- 1). Make two holes in your clear container. The holes should be the same size as your screws or rods, or slightly smaller. You can use a drill, or you can simply hammer or poke the screws or rods through the container, or use another method.

Place one screw or rod in each hole. - 3). Add baking soda to the water. Add plenty, but make sure it doesn't collect at the bottom. Stir the water up to ensure the baking soda is dissolved. You can either add the baking soda to the water in a bowl or pitcher, then pour it into the container, or fill your container with water and then add the baking soda if your container has a lid or cap hole large enough to allow you to stir.
- 4). Connect your battery or batteries to the screws or rods. If you use two batteries, connect the positive end of one battery to one screw and the negative end of the other battery to the other screw. This will cause an electrical current to flow through the water. You should now see bubbles coming from the "negative" screw. You may also see a few bubbles coming from the "positive" screw. The "negative" bubbles are the hydrogen gases created as the water separates into individual elemental atoms. Bubbles coming from the "positive" screw are oxygen gases.
