Does anyone know how to build a trebuchet out of masking tape, straws, weights, and paper clips?

It's for my science class and I just need suggestions.Does anyone know how to build a trebuchet out of masking tape, straws, weights, and paper clips?
yes





2 A frame supports sides - make sure there's plenty of straws for nice thick support %26amp; steady base.





then have a pivot/axle again good and strong





u also need a strong throwing arm with basket for masses at one end.





presumably u could then use your masking tape as the slingshot that lies back along under the throwing arm - for hurling chalk/projectile.





basket for masses should be at front of machine, when this drops it drags masking tape sling out round and over top of throwing arm
