How Do You Make a Catapult with a Wishbone?
You can make a toy catapult from a wishbone, matchstick, rubber band and stick of gum.
- Chicken wishbone
- Rubber band
- Matchstick (might also work with a toothpick)
- Gum (might also work with Play-Dough, clay or silly putty)
- Chew gum
- Turn wishbone so that curved part is up and wide part of connected end is down
- Stick gum under wide part of bone at the connected end
- Loop rubber band across the two unconnected ends of the wishbone
- Thread matchstick between the strands of the rubber band
- Wind rubberband up by turning matchstick
- Stick one end of the matchstick to the gum, under the wide part of the bone
- Wait a few minutes.
What Should Happen
Within a few minutes, the wide end of the wishbone will release from the gum. The matchstick, under tension from the wound-up rubber band, will fling the wishbone in the air.
The movement of the wishbone is like the movement of a catapult, pulling away from the gum.
Experiment by putting small bits of paper on the end of the wishbone before it releases to see how high they will fly.
