Hydrogen Bottle Rocket Experiment: To help us understand the concept of reactions and their products, we performed a hydrogen rocket experiment. For the experiment, we used an I.C.E. table to determine the amount of each molecule that we would use for the reaction. The materials we used were water, an empty two-liter soda bottle, tube, fire source, hydrogen gas, and oxygen. In the experiment, filled a plastic bottle water, used a tub filled with water, placed the bottle upside down into the bowl and lowered it, placed the tube into the bottle neck opening, filled the bottle with hydrogen gas, carefully lifted the bottle from the water, keeping it upside down, allowed air to enter remaining area, and placed cap back onto bottle. We then took the bottle outside and placed it onto a launch pad. We removed the cap and lit the mixture inside the bottle. The gases react with a loud bang. We then observed. We found that the expanding hot gas pushes the rocket making it fly. The water is pushed out the back, causing the rocket to launch into the air.
