Yoqanr Newton's Cradle Physics - 7 pieces

Be sure to be gentle when unpacking and installing to avoid winding! 1. Gently remove the base and rod from the box. 2. Remove the rod from the bag without removing the center foam. 3. After installing the pole to the base, remove the foam at the end. Gravity At Work :See before your eyes as the Newton Balls transfer fall and transfer weight across the gadget. Drop one ball or two balls. You can see the energy transfer in such an astounding way! Review: Perfect for the kiddo's science project! - Cheap junk. 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.
