Toys and Games Reviews of Newtons Cradle 7 1/4 inch
Customer Review: Eh...
Summary: 3 Stars
Like the title says, Eh... nothing special. It hasn't broken yet, so that's good. The strings seem a bit flimsy. It's of mediocre quality, but then again it was a pretty good price. The only reason I gave it a 3 overall (and a 4 as educational) is because it doesn't display the conservation of momentum and energy as aptly as the ones I grew up with. The balls seem to bounce around a bit, and the ones in the middle, which in theory should be stationary (when only the one outside ball is retracted and released) seem to still move a bit. Also they will only bounce back and forth displaying the previously mentioned principle for 30 seconds or less. In contrast (so you know where I'm coming from), the ones I grew up with were of a bit higher quality, the middle balls would be completely stationary when they were supposed to be, and the thing could go for up to 10 minutes back and forth before beginning to slow down and stop. While not to excited with the product, I can't same I'm disappointed, especially for this price.
Description of Newtons Cradle 7 1/4 inch
Newton's Cradle is a timeless, classic desktop science "toy" that is the perfect blend of science and art. Lift one steel ball and allow to fall back at one end, the ball at the opposite end will swing out the same distance. Stylish chrome and black color scheme. Fascinating to watch. Also known as "Balance Balls", "Newton's Pendulum" and "Newton's Balls", this executive office toy demonstrates the law of conservation of momentum. Using Newton's third law has never been this much fun! What happens when you swing two? Or three? Newton's Cradle was invented in 1967 by English actor Simon Prebble and named in honor of scientist and mathematician Isaac Newton because it employs Newton's Laws.Toys and Games
