David Webb And His Special Vacuum


LOL This tuesday we had a guest speaker named David Webb, who I actually thought wouldn't be as interesting as his presentation. He used a vacuum, and with it, he demonstrated many different situations where how our atmospheric pressure is different than if there is almost no pressure at all. This fascinated me very much, and I thought that his presentation was very good. By experiencing the reactions of different pressures, I have begun to have a better understanding of how pressure can affect things in our world.
VACUUM!
