I got this science kit because many of my mom friends have been talking about this brand lately. I have 3 and 6 year olds at home, both eat slowly. We experimented together to find out how food is digested. This does exactly what I was hoping for. This experiment was a brilliant idea! They loved every minute. The instructions could be clearer. We casually added an important and fun step. After making the slime with our own hands, we squeezed it out of the package. The slime alone kept her busy for an hour and we had to return for two more projects the next day. The imaginary "porridge" was fun to shred and super easy to peel off!
