To prepare your plywood supports, take one rectangular piece of plywood 1/4' to 1/2' thick, 15' by 18 and 1/2', and cut it diagonally into two equal triangles.
#Simple catapult how to
(Google how to make a catapult for kids). You might try online research and/or trial and error. Intro Young Engineers: Pyramid Catapult - Easy and Powerful DIY STEM Project for Kids STEM Inventions 15. Hot glue is fast to set and has a bit of flex to it. For the base of this catapult, you will use a 2x4 base supported with plywood triangles. Research: Research different ways to build simple catapults. This design does call for hot glue - I don’t think you can get this secure with just rubber bands anymore. We just turned the catapult on it’s edge so it has a vertical orientation, then added a stable base. Here’s how we fixed the rather lame-o Spoon-a-pult. Mitch and I scoured the web for a better popsicle & spoon design, but it seems that many STEM & craft bloggers are either happy copying the same dang design everyone else has done…or moved on to different styles of catapults that are WAAAAAAY more complex. Annoying, right? Tinkering with Basic Catapult Design If you’ve ever made one of these, you’ll notice that they fire pretty much straight up. We built our first one years ago from a design found at the Magic House’s Maker Workshop way before noticing them online. You’ve probably seen the classic Popsicle and Spoon Catapult - they’re all over the internet! It’s a very simple machine that’s great for introducing kids to STEM concepts and physics. Do you want to build a powerful spoon catapult - using simple household materials - that can shoot marshmallows 15 to 20 FEET? Of course you do!
