Rubber Sheet
The Rubber Sheet, a "trampoline" introduced by IndustrialCraft 2 Classic (IC2C), is crafted out of 6 Rubber (or Rubber Balls), and can act as a trampoline. To correctly function, requires at least one block beneath it to be air and "support", or solid blocks, around it. Trampolines can be any size (as the blocks "link"), and when jumped on from any height, bounces you up, similar to the vanilla Slime Blocks.
Resign Sheet
The Resign Sheet, rather then acting as a trampoline, acts as a damage reducer. When fallen upon, the Resign Sheet absorbs 25% of your fall, making it ideal in 3 or 5 block jumps to negate damage. To create the Resign Sheet, right-click a block with Sticky Resign (tapped from a Rubber Tree), and the Resign Sheet will be placed.
