For a school project I have to build a device made of only toothpicks and glue gun glue that will hold an egg. The device will be dropped 5 meters and the egg must not break, so the idea is to build a device with a good crumple zone. I have a few ideas about how to build it but its pretty hard to find advice on how they are made, I can only find info on how they work. Oh yea it has to have a mass of 50 g or less, thats a lot of toothpicks. If someone could comment on my ideas, or suggest different variations it would be great. Here are my ideas. 1. Build a crumple zone where the base is made of squares each connected to a square above them by 4 toothpicks. 2. Same idea as above but use only 2 toothpicks to connect squares (therefore its weaker, which means I can have a longer crumple zone right?) 3. Make the base triangles that are connected to above triangles with 2 toothpicks. 4. Attempt to make it a shape sort of like a blimp? I have my doubts on this one.
