The lab bench is covered with beakers, test tubes, and a handwritten challenge card: 'Make an egg float.' Simple enough, except the rules say you can't touch the egg, change its shape, or use anything but what's on the bench. You spot the salt, the water, and the graduated cylinder. The principle is buoyancy — but knowing the science and proving it are two very different things.
