Try bubbles! I'm not kidding!
My colleague found a fabulous idea for using bubbles in this book:
The kids had a BLAST!!!
All you need are plastic plates, straws, bubbles, and rulers! Once the kids get started, they don't want to stop! See for yourself below!
And of course...giggle, giggle, he he he! They were all cracking up at this one...the "booty bubble!" (When I look at it, I see Garfield, the cat. Do you?!)
And the biggest one of all!
