Putty's

During class we created silly putty's. The used common materials to create these putty's. The materials we used were, glue, water, baking soda and some sort of acid. At procedure required use to mix a moderate amount of each of these. At the beginning it was a very slimy substance, but as it had more and more contact with the air it became stiffer, but it you can still shape it. Something interesting I found out, was that it bounced when it was formed into a ball.
