Webber

Wow. All I can say is wow. I had so much fun with the guest speaker. He was so much fun to work with. I just thought it would be just another lecture but it was the complete opposite. They were unbelievably great to have around. He had so much energy and was very inspirational. I never got bored with what they did. The labs that they did were so much fun and was the opposite from what I expected. My favorite and most funny lab was the one with the marshmallow. This already big marshmallow doubles it's side in the chamber but when the gas is released back in the chamber the marshmallow shrinks double it's size. It was so funny because of the expression Brijesh made. It just made the lab that much more enjoyable. This was a very good boaster for chemistry and makes me want to learn more.

Crushed

We just did a lab where we got to crush cans well we didn't do it with our bare hands but we did crush hands. Let's just say we got to crush cans without any force of our own. We used pressure. Well to be exact we used air pressure. It was really cool. The first time we did it we had no idea what we were doing but we were totally shocked when it happened. The lab consisted of a empty can a hot plate and a little bit of water. So we put a little bit of water in the can and we put that on the hot plate. With that we let it steam out all of the air. When we believe the air is mostly all gone we quickly in one movement put the can into cold water with the openning down. With that the can crushs in on itself. We couldn't fathom it the first time we tried it but once we did it over again twice and three times we kind of got what was happening. We believed that the air inside the can was pushed out from the steam that was coming out. So we we exposed the can to the air pressure in the water we crushed the can. Since there was no air pressure that was pushing against the can from the inside the can would just crush from the pressure from the outside. It was all very fascinating.
