In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge. Use this activity to introduce learners to how specific shapes like arches provide strength and stability to structures. Also, this egg-related activity could be integrated into any Easter or Spring themed programming. This activity guide includes a helpful video that demonstrates each step of the activity.
