On Wednesday the 27th of May Mr. Wallace came to our class to show us how to make hydrogen gas. While Mr. Wallace showed half the class how to do this Mr. Martin took the other half of the class out of the class room and measured the speed at which a tennis ball went at when dropped from a certain height. When making the hydrogen gas we had to wear safety glasses to protect our eyes from the gas or it would burn them. As soon as we had added sodium carbonate to tin foil & water it started fizzing. Then we put tinfoil over for a few minutes. Next we were told to put a hole in it then hold a lit match over it. Boom!!!!!!!! Boy we jumped it sure was loud Mr. Wallace told us it was because hydrogen gas is very flammable. Then he turned to our groups and started coming to the groups one by one. Then it was time for the last group and it made the largest bang out of all of them. All in all it was a great experience.
