Instructions
Insert one short yellow Tinkertoy rod into one of the holes on the perimeter of a Tinkertoy spool. Press it into the hole to ensure a snug fit. Connect the free end of the yellow rod into the side hole on another spool.
Attach two long orange Tinkertoy rods to one of the top holes on the spools so the rods point almost straight up from the spools.
Tie four long rubber bands together into a chain. Attach each end of the rubber band chain around the ends of the long orange rods by looping the first and last rubber bands in the chain around the orange rods to finish the bow.
Make an arrow, if desired, out of one long orange rod, one short yellow rod and one coupling. Attach the yellow rod to one end of the coupling and the orange rod to the other end.
Position the end of the orange rod in the center of the rubber band and pull back to launch the arrow from the bow.
