Silly Putty

So at Jonah's party, one of the prizes was Silly Putty. Of course, that was the one I chose. I've been having so much fun with it, even though it's just like Play-Doh. The only thing I like to do with it, is make air bubbles, pop them, and then they make a loud noise. It's really cool. You wanna know how to? Well, all you need is a ball of Silly Putty, or something with the same consistancy as Silly Putty. Here's how you do it:
Make your Silly Putty into a perfect ball. You can test its perfectness by bouncing it on the ground. If it comes straight back up to you, then you're good. If it goes in some other direction, then keep rolling it. Next, take your thumb and stick it through one side. Don't go all the way through. Then, carefully take your thumb out. There should be one closed side, in the shape of your thumb, and one open side. Close up the open side by sticking it together. Becareful not to squeeze your thumb print. Lastly, hold it in your hand and squeeze as hard as you can. It'll make a loud popping sound, kinda like when you step on bubble wrap.
Now, go try it!
