When Krayden finds things that is thinks is cool we hear about them for days. He got a little book about the earth and and there was a part about volcanoes. We heard about volcanoes for weeks. We looked them up on the Internet and researched them. When we were at target and saw "air dry clay" we knew it would be perfect to show Krayden how volcanoes really work. Dad and Krayden spent a afternoon making their volcano and after it was dry we pt it to the test and it was a success.
