A common school activity, perhaps for a science class, is building a container for an egg so that when the egg is dropped from a very great height, the egg will not break. The rules vary for each school or competition, but, generally, participants are required only a limited amount of materials with which to construct the device. Often the lightest device (or the one that uses the least amount of material) that still keeps the egg safe is declared the winner.

Check how big your egg drop device is allowed to be. If you are participating in a competition, there might be rules about how many inches across the final device can be or how much material you can use. One example of a successful egg drop device is to use straws to house the egg, so the straws absorb the impact, protecting the egg.
Sketch out a few ideas of how the final device should look. For example, securing the egg into one spot in the device works better than letting it roll around freely. For more ideas, check out Chris Eckert's video of egg dropping at niemworks.com -- please see the link the Resources section.
Build a standard straw egg drop device, if that's your choice, by making a cube out of straws that the egg can fit into.
Stick straws into the cube with the egg, so the device begins looking like a pincushion or porcupine. Secure the first few straws to the cube with tape, but as you use more straws, the tightness should keep them secure enough.
Test the device. Did the egg break? If so, make some modifications. See where the egg broke or cracked. Did a piece of the device not protect the egg like it should have? Did it fall apart upon impact? If you built the basic straw design, did any of the straws fall out? Restraw and retape the device where needed or add more protection around the egg.
