This is a great collection of science gadgets that will allow explorers young and old to discover the mysteries of magnetism, gravity and light. The kit includes a set of ring magnets that appear to float on a central post due to the opposing poles of the magnet. Flip a magnet and they attract. The acrylic prism will let you split sunlight (or a bright focused indoor light) into a full colored rainbow across a wall or ceiling. It can also reflect an image within the prism much like a periscope. The Gyroscope will spin on its pedestal, balance on the included string tightrope or spin perfectly on the lip of a drinking glass. This collection is a great addition to any classroom or a home lab. For ages 6 and up with adult supervision.
