Here's my riddle, then. It's more on the lines of Simon's because I'm terrible at every other sort. =P
You need to drop an egg from a height of three feet without it breaking. You can build something around the egg (not on the floor) to keep it safe, but your only materials are pipe cleaners, cardboard, cellotape and elastic bands. What would work best? Feel free to answer with a diagram if you like. =P
