Cupids Bow and Arrow! LOL Popsicle stick bow and arrow! Soak the stick in water for a few hours, bend, tie string into grooves, cut q-tips with a small groove and shoot!
Craft Stick Catapult - my awesome Cub Scout companion leader used this to teach Leave No Trace: need 7 sticks for outdoor code rules, and signature. Band 5 of the sticks, band 2 of the sticks.
