Library Type Public Description: “Springtime is egg time. They’re everywhere: closely guarded in the nests of birds, decorated as gifts and filling the shops as chocolate Easter treats. An egg is a universal symbol of fertility and new potential, and their perfect curved surfaces give them an instantly recognizable shape. But that shape hides a conundrum. We often describe fragile things as being like eggshells, because the thin fragments of a cracked shell are so frail. Yet a hen can sit on an egg and not break it; you may have seen demonstrations of people squeezing eggs in their hands and being unable to crush them. An egg is at once extraordinarily strong and hopelessly weak. How can this be?” In our Maker Monday STEM Class, we are going to take a look at how the strength of an egg comes from the shape by doing several experiments, including walking on them! |
