Expanding World of Gases

How do you crush cans by using only gas pressure? Can you break a stick with only 1 sheet of newspaper? Do hot gases act the same as cold gases?; Do hot and cold gases take up the same amount of space? We’ll lift you off the ground with only plastic baggies and straws - hey you can even lift your teacher! How do you get an egg stuck in a jar and remove it using only gas pressure? If that’s not enough, you’ll build your own hot air balloon and we will fly them on the last day of class. Don’t miss out on the fun!
