8. Walking On Eggshells
No need to worry about walking on eggshells with this investigation… that’s the whole point! Grab 2-6 dozen eggs, a black plastic bag (just to be safe), take off your shoes, and watch how the seemingly fragile shells can actually withstand a surprising amount of weight. What’s the secret? The egg’s arched shape gives it tremendous architectural support. For more details on conducting this sturdy experiment, check out Steve Spangler Science.
