BUT that is exactly what we needed for the kiddos science project. Worked perfect!! And for roughly $10 it was spot on. Would buy again if needed. Five stars all day. Review: Don't expect miracles - Well not sure if my expectations of this was over blown or if it actually isn't made correctly. My understanding of this kinetic energy machine was start the energy and it will run for along time. Well after about two minutes it slows down and then stops.
