6/19/17- STEM Activity: Marshmallow Catapult

Happy Summer!  Have fun building this Marshmallow Catapult and googling tension, torsion, and gravity, which are the forces involved when catapulting an object.

Supplies:
7 Wooden Skewers
1 Rubber Band
1 Plastic Spoon
Masking Tape
4 Large Marshmallows, plus marshmallows for shooting

1) Use 3 marshmallows and 3 skewers and form a triangle for the base.
2) Use 3 more skewers and 1 more marshmallow and form a pyramid.
3) Tape the plastic spoon to the end of the remaining skewer.
4) Loop the rubber band around the topmost marshmallow.
5) Insert the spoon and skewer combo through the rubber band.
6) Connect the skewer and spoon combo to one of the base marshmallows.
7) Put a marshmallow into the spoon and shoot.
8) Try shooting the marshmallow again, but this time pull the spoon further back.  Did the marshmallow go further? Did the marshmallow go higher?
9) Try other adjustments to the catapult. How far can you get the marshmallow to go?  How high can you get the marshmallow to go?
