we were not able to go through with the magnetic propulsion experiment. so we are going todso an experiment that will help us decide whether or not fiberglass is really the best insulation for a new house or not. we will have four big containers containing either sawdust, rice, fiberglass, or nothing and in the middle we shall have smaller cups that all have ice in them. this experiment will show us which type of insulation will keep the cold in best. brian is getting the fiberglass and i am getting everything else.
