This classic physics experiment is a really fun one! You get to create a descent vehicle for an egg dropped from a great height that helps the egg land gently enough to avoid going SPLAT!

Instead of testing design iterations on precious eggs, we can first prove out our vehicles using the CLUE board! It's packed with sensors and has a display and speaker for feedback -- we'll use those to study the impact g-force of our landing. Once we're satisfied with the data, we can swap out for the more fragile ovoid!

Here's an excellent video by Mark Rober explaining the physics behind the egg drop as well as showing five designs you can try out. Instead of testing on eggs each time, we will first determine the g forces sustained on impact with our CLUE board!

We really don't want you to break your CLUE board -- so be sure to test out your experiments in stages and ideally on softer surfaces before building up your confidence in your design to try it from full height over a harder surface!

Do you feel like you just don't have a CLUE? Well, we can help with that - get a CLUE here at Adafruit by picking up this sensor-packed development board. We wanted to build some...
