On Tuesday , we had a guy named David Webb come into our chemistry class and talk to us about pressure . He did some pretty interesting things with pressure , using this air vacuum thing to melt marshmellows together , crush a 2 liter soda bottle , and to pop a small balloon . It was pretty cool . It's amazing what you can watch and learn when you watch someone who has been doing it for years , show you how it's done . I hope we can have more guest speakers like him , come and show us the material we are working with .
