This is my first instructable so please be nice.
I made this catapult because I was bored and decided to do a instructable of a meccano catapult.
Pros: it has a strong framework and doesn't fire straight down.
Cons: bad pictures and doesn't fire really far.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Step 1: the Frame Work.
These are some angles of the framework.
Step 2: Step 2: the Box.
These are a couple of angles of the box.
Step 3: Step 3: Attaching the Pieces.
Just follow the picture.
Step 4: Step 4: Loading and Firing.
To load, put spacers or random things (not too heavy) in the box.
To fire hit the end without the box on hard (but not too hard).
It will then hit the lower beam, stopping it from firing straight down.
