Desktop Catapult – Sick Science!
An awesome physics and motion tool
Since city ordinances (among other things) won't allow us to build a full-scale Medieval catapult, we had to scale it down a bit. Despite the setbacks, we've come up with a pretty sweet, indoor-safe Desktop Catapult. And the best part is that everything you're going to need can be found right in your home. The Desktop Catapult makes for a fun way to explore the properties of physics and motion.
- Staple remover
- Solid, flat base (we found that a 3-ring binder works great)
- Plastic spoon
- Hot glue gun or tape
- Catapult-able objects
- Apply an ample amount of hot glue to the bottom (wider claw) of the staple remover. Press and hold the staple remover against your base. (If you are using tape, make sure that you have the staple remover secured to the base.)
- Apply a strip of glue to the top side of the staple remover and press the spoon onto the top of the remover. The end of the spoon handle should be lined up with the non-clawed end of the staple remover. Be sure that the spoon is secured to the top of the staple remover. (Again, if you are using tape, make sure the spoon won't be able to break free.)
- You're ready to launch! Put an object like a tin foil ball or a small piece of candy in the bowl of the spoon.
- Gently pull downward on the bowl of the spoon. Make sure not to get in the way your projectile.
- Let 'er rip!
