Think bungee jumping looks scary? Knowing the science behind bungee jumping might make it less so. Using an egg and rubber bands, young engineers model bungee jumping. They test the distances that the egg falls for different numbers of rubber bands, then use the results to estimate the number of rubber bands needed for the egg to fall two meters without actually hitting the floor.
