Rubber Sheets are an advanced use for Rubber provided by IndustrialCraft 2.They have two main purposes: negating fall damage, and bouncing on them like a trampoline. This dual purpose could make for an interesting way to get into a base with an entrance high off the ground.

The rubber sheet is a highly advanced piece of rubber capable of doing an amazing thing. Bouncing you! Jumping off of a height onto this rubberized sheet will cause you to bounce back up, effectively negating fall damage while having fun! May not prevent injury from 11 block falls. The Rotary Macerator is an upgraded version of the Macerator. Depending on how long it has been operating, the Rotary Macerator can be much faster than the Macerator. Applying a Redstone current, like with the other Advanced Machines, will increase its RPM, but will constantly draw power. The Macerator will gain speed when it is actively grinding items, or when it is fed a Redstone signal, and it will lose speed when neither of these are present. Speed is lost at 4x the rate it can be gained. A 0% speed Macerator requires 4000 ticks to process an item, however a 100% speed Macerator requires 12 ticks to process an item.
