Building a K-Nex Ferris Wheel

Today in science me and my mom built a k-nex ferris wheel. The cool thing about it is, you can put your lego people on and when it spins the people stay on. There is a special electronice thing that makes the whole thing move. We are going to get  a new set of nine volt batteries. k-nex is made by a company called Brio. It spins very smoothly and the seats to put the people in are awesome.
