Crash Test Cars

Crashing cars, sounds fun right? While we think so too, we are upping the stakes and asking you to not only build a car to crash but find a way to keep an egg safely inside of it. This is an easy STEAM/ STEM challenge that is perfect for all ages. While Isaac teaches you how to build a simple car, it’ll be up to you to decide how to keep the egg from cracking open in your car.


  • 4 wheels, 1/8″ axle

Crash Test Car Challenge!

Now that you have built your car and secured your egg within the car, it is time to crash it! Take your car and crash it into a brick wall. Seems simple right? But wait, the real challenge is to keep that egg from breaking when the car smashes into the wall. You can secure your egg any way you want. Isaac suggests a few ideas in the video, such as rubber bands or little cups. When you are done securing your egg, set up a ramp near a brick wall, or even just the side of your house, and let your car go!
