In my classes, I just used a couple of books and a piece of paper. Put the books on a desk about 2 inches across and lay the paper across the gap. Blow through the opening, the paper will suck down into the gap. It's too simply a process to use your example in class.

Yes! That is a great example.

Very nice! And don't forget how to remove a cork from a wine bottle with a plastic bag!

How? That would be cool to do.
Thanks for sharing another fun way to demo science principles. Love that you used this to build up to rockets. :)
Thanks! The kids always get a kick out of doing these with their own bags. Sometimes it is a demo, sometimes each kid gets their own, all depends on funds. Great fun either way.
