I managed to get back to the car before my wife had finished shopping so I had 20 minutes to test the catapult launch on the plane.
If you have a question it is probably worth reading this video description first because the answer may already be here. To help you find my videos I made two search guides https://youtu.be/ceBSOoOHcgw or https://youtu.be/Zj4UgwkwYRk or checkout my playlists page https://www.youtube.com/user/GrandadIsAnOldMan/playlists?flow=grid&view=1

Polystyrene Pizza Trays
Glass Fibre spar from a cheap kite
Clearly many parts of the world do not have polystyrene pizza trays. They are just the packaging that my local supermarkets use for pizzas. I use them because they are free and would otherwise be thrown away. You could use any polystyrene or styrofoam packaging you can find or even buy foam board from model shops. The foam I am using is about 5mm thick.

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
