The egg drop

In today's experiment we did the egg drop so to do this experiment you will need to have 1 cup some water a flat tray or a plate 1 egg and 1 cardboard toilet roll so then you put the water in the cup and put the tray or plate on the top. Then get the cardboard toilet roll and put it facing up. When you got the egg put it in the middle and then hit the plate and the egg goes into the cup if you are lucky.

This is based on Newton's first law of motions and the point was for the egg not missing the cup.
