In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open. Learners will discover that hard-boiled eggs are much easier to stop spinning because they are solid, whereas the liquid inside the raw egg prevents it from stopping and provides enough drag to start the raw egg spinning again. You can demonstrate that the eggs are really hard-boiled or raw by breaking them open in front of learners. This activity guide includes a helpful video that demonstrates each step of the demonstration. This egg-related activity could be integrated into any Easter or Spring themed programming.
