hours of fun

I brought this for my onw grandson for his birthday, it was a little expense, but I knew what they look like.. The boys had seen them at
the Lancaster Science Factory.. My husband and I also enjoy playing and forming different disigns and such things as boats and airplanes.
It is a good learning tool. I plan on getting a few more, so the two boys can experiment more.
