What happens when you apply force to an object? You already know that some materials can change shape but bounce back again - springs, rubber bands and balloons. But other materials stay in their new shape. If you push or pull on dough or modeling clay and change its shape, what happens? It stays in the new shape. You can use force to mold dough and clay. It is good fun. It is also good science.
