Rubber Sheet

The Rubber Sheet, also known as Rubber Trampoline, will cause you to bounce when you fall on it. There must be a one block space underneath the sheet, and it needs to be connected to blocks on at least two sides for it to function. This has the effect of negating fall damage, as your bounces will gradually decrease in height until you come to a stop. If fallen on from heights over 11 blocks the sheet breaks.
