Bungee Jump ... With Eggs!
Does the mere thought of bungee jumping make your palms sweat? How about DIY bungee jumping at home with your kids? Don't worry, there won't be any broken limbs involved...just broken shells. In place of your child, an egg will be doing all the jumping.
The nylon pantyhose you'll use for this experiment has a natural elasticity and works like a bungee cord; the force of the falling egg causes it to change its form, but the strength of the fabric pulls it back. As you measure and conduct test runs, you'll be working out the components of Newton's famous physics equation: force = mass × acceleration. But before you jump into this experiment, be warned: it may get a little messy.
