5.0 out of 5 stars The Best Newtons Cradle, 15 Sep 2010
= Durability:5.0 out of 5 stars  = Fun:5.0 out of 5 stars  = Educational:5.0 out of 5 stars 
I previously bought one of the other smaller newtons cradles on amazon, it was nowhere near as robust as this thing. The old one broke after my brother pushed it off the desk by mistake (one of the nylon strings snapped). This one has a sturdy frame and base (most do not have bases) and the system loses energy less quickly than my last cradle (one of those silver stand ones with no base). This better demonstrates the principle of conservation of energy. If your a physics teacher and want to use this as a demonstration then this is the cradle for you. If you want it to just sit on your desk like I do, it might be a bit large (18 x 18 x 12 cm) if you have a small desk, but otherwise id still recommend.
