The hypothesis is that as the size of the hydrogen foam bubbles increase, the energy released in the combustion will be greater.

You will attach a lever to the hydrogen tank, fill a basin with liquid soap and water, and attach a tube to the lever. You will adjust the rate of hydrogen gas released into the soap mixture and vary the filters used to create bubbles of different sizes. You will then ignite the bubbles and observe the combustion that results.

You will need a tank of hydrogen gas, a flow control valve, tubing, a large basin, liquid soap, water, a lighter, a ruler, and various filters.

The results showed that no combustion took place for hydrogen foam bubbles that were less than 4mm in diameter. However, as the bubble size increased beyond 4 mm, combustion occurred, with increasingly larger flames as the bubble diameter increased. When the size of the bubbles were more than 18mm, the combustion became explosive.

This science project is interesting because it explores the potential of using hydrogen as an alternative fuel source. It is unique because it looks at the effect of bubble size on the intensity of the combustion.

Experiment variations include using foam from a fire extinguisher and using the hydrogen foam bubbles to fuel a small rocket.
