These craft stick catapults are very easy to make and provide hours of fun as well as being a brilliant engineering and design project. We made ours space themed and turned table tennis balls into planets.
Catapults are also great for a maths based activity if children record how far different size/weights of balls travel.
The catapults are very easy to make, each one takes only a couple of minutes to build once you get the hang of it.

How to make a catapult
- Start with about 7 lolly sticks and place them on top of each other. Twist an elastic band around each end to hold them in place.
- Place another stick above and one below the stack of 7 so they make a cross shape. There should be more lolly stick on the end you want to use for the milk top.
- Tie an elastic band around the middle of the cross.
- Twist another elastic band around the bottom of two sticks as you can see in the photo.
- Attach a milk bottle top using double sided tape or strong glue.
- Experiment with your table tennis balls.
Investigation Ideas – remember to only change one variable at a time
What happens if you add more or less lollypop sticks to the central core of the catapult?
What happens if your catapult end is shorter?
Does a heavier ball travel further?
How far can you get a ball to travel?
What happens if you make the ball heavier?
