This past week I had the opportunity to go inside a large plastic bag and have the air sucked out. Why would I do this? I did it because this demonstration was about air pressure. When the air is sucked out of the bag, one feels the combined air pressure of 14.7 psi. It is much stronger that you would think.
Some of the students also took turns going into the bag to experience the air pressure. It was quite an interesting day in science class.
Looks like lots of fun, Kevin! Did you use a shop vac to suck out all of the air?

Hi Claire,
Yes, I used a shop vac–missing one wheel, and a very large plastic bag.

Dillon,
Thanks, I looked at the graphics you sent me: they look pretty good. I like the rocket and atom but I’m not sure how to place them in the logo. I’m sure I’ll like the final design.
