In the experiment hydrogen and the bubbles were put together and was set on fire to see what would happen or anything new would occur. Since We cannot see hydrogen because the element is a gas, the gas is put in with the bubbles. The bubbles are made from soap and the reaction would be different then, just lighting the hydrogen on fire. An interesting factor is the pressure of each bubble, due to its size is also how the reaction would be different or the same when lighted by the fire. The smaller bubble exploded on fire and much wider. The bubble that was lighted was large and did not explode on fire as wide than the smaller bubble did. The surprising factor is you would expect the fire to go down because we think logically of the oxygen burning
