A classic and inexpensive childhood toy that launches high in the air. Just turn the hopper inside out and quickly place it on a flat surface. The hopper will slowly begin to revert to its original position, rocketing into the air as a result! Scare your friends by placing a loaded hopper near their person, or buy a few and have a hopper 'race' to see who can get theirs to launch the highest, whether by a secret technique, or by experimenting with different surfaces as launch pads. Makes a great party favor or gift for a classroom contest!
Note: This product comes in assorted colors, as you can see from the second picture. If you would like a specific color, please indicate which in the comments while placing your order and we will do our best to accommodate you (no guarantees, but we can follow requests as a general rule).
