This may seem like magic to kids but the wand can be used to display the attractive properties of magnetism to other magnets and metal objects. Use with Wire Rimmed Counting Chips, Iron Filings and playing bingo. Ages 3 and up. Measures approximately 8 L x 1 W x .5 T inches. Keep away from Computers and Gadgets.
