Catapult Writing




Our mission was to create a catapult that would fire a tin foil ball. The  materials we had were  15 popsicles and 12 rubber bands and one spoon.  

 

What me and Benny did was stack about 15 popsicle sticks on top of each other then put some rubber bands around the ends of the popsicle sticks so they wouldn’t fall down. Then we put a spoon through the middle of the pile so it was wedged in there tight. 

In the competition ours went really far but after it wouldn’t work. Ours won by about 2 meters. (past second place) 


The way our’s worked was you pushed the back down and it flicked the tinfoil ball. 


We originally wanted to go all for looks and not care how far it went but all the designs we found used hot glue so we decided to just build something that could at least shoot. For that design you hit the spoon and it launched but it only had height. But then Benny fingered out that if you held the spoon down so it was bending it would launch much further.

Next time I think we should make a proper design

But with popsicle sticks.


P.S. I think the wind died down for a second while we shot the catapult.






A fun afternoon
