![]() The magnetic fields interact with each other and Marie spins and dances. Marie has a heavy round base with a magnet and a rectangular mirror that also has a magnet. The company that made these has gone out of business, but play with one if you get a chance (there are videos of her on YouTube!). What happens to the ball that has just hit? Another similar toy is Newton’s Cradle. You put energy in the system by rotating the handle. When you get them moving, if one hits the other, all the energy is transferred to the second ball. Try actually holding it and giving it a good spin. Pushing the other side will make it spin in the opposite direction. If you push on one side it will spin in one direction. Notice that it is not symmetrical on the bottom. There is a coil of wire in the base, which acts as a magnet with the current from the battery. Top Secret has a battery in the bottom piece that sets up a magnetic field with the spinning of the top.Tops spin on a small point cutting down on friction that allows the top to spin longer. Friction would slow down the spinning motion. Does the ball still float? This experiment will also work with a beach ball and leaf blower! Try rotating the pipe so the blown air is not going straight up. This sets up a difference in air pressure around the ball. The stream of air is below the ball, then has to “split” and go around the ball, then join back together above the ball. Blow air into the tube and it lifts the ball. Start with a pencil or pen, then try less symmetrical objects.īernoulli demonstrator or the floating ball. Try to find the center of gravity of objects by balancing on your finger. ![]() For this bird, the center of gravity is on the beak, allowing it to balance and even spin without falling! Notice how the wings are heavy and flared forward. Instructions for physics toysīalancing bird.

If powerful magnets are swallowed, they attract each other internally and cause extremely serious injury. Never let any child under 6 play with magnetic toys unsupervised. The physics toys for experiments use magnets and very small objects. Safety note: Be sure to explain safety precautions to children. Make them educational by learning the science behind them! Here are some STEM activities from my collection. That means many toys can be physics toys! Toys are interesting and motivating for children. Physics toys are toys whose action can be explained using physics principles.
