Funny Putty!

Funny Putty is elastic. That means it can bounce and stretch. Funny putty can also pick up print from the newpaper. Many substances are elastic: rubber, chewing gum, taffy, etc. It's fun to experiment with elastic substances to find out what they can do. You can make Funny Putty for fun, or give it to a friend as a gift! How many things can you find to do with it?
