Lesson 20

Marshmallow Catapult

Here’s a project that you can build and use to learn about engineering
terms such as force, trajectory, tension, and of course the theory that once
an object is in motion it tends to stay in motion. Oh who am I kidding,
here’s a cool project to build so you can launch marshmallows into the
air like scud missiles!

Again, like some other projects in this book, there are not a lot of parts to
puttogetherbutthingshavetobedoneinorder.Particularly,allthe
holes have to be drilled precisely where shown in the diagrams in order
for the catapult to work properly. Remember, measure twice cut once
(and drill once).

Here’s the cut list for our project:

Handle: (1) ¾” x 1” x 7”

Side panels: (2) ¾” x 5 ½” x 6 ½”

Long boards: (2) ¾” x 1 ½” x 14 ½”

Catapult arm: (1) ¾” x 1” x 10 ½”

Tall spacer: (1) ¾” x 1 ½” x 5 ½”

Short spacer: (1) ¾” x ¾” x 4”

We pieced our catapult together with wood
scraps left over from other projects and you can
probably do the same. If you do need to buy
