Today in gifted classes we made marsh mellow catapult out of marshmallows, rubber bands, spoons, and popcicle sticks. What my group did was we tried to use all seven sticks. So at first we used 3 sticks with 1 rubber band and the spoon. First we set the spoon o top of the 3 sticks. Then, we tied the rubber band and set the marshmallow in the spoon and we pulled back on the spoon. Woosh there it went 2 inches far from where we shot it.
