1N10.20 - Egg in a Sheet
An egg thrown at a loosely held sheet will not break no matter how hard you throw it.
An egg is thrown hard, so it arrives at the sheet travelling at a high velocity. However, the sheet is loose and is able to "absorb" the impact of the egg and distribute the force of the collision over a longer time. Increasing the time of the collision reduces the force at any given time, thus preventing the egg from breaking.
