This mod is very simple in what it wants to do. Simpily, it adds Rubber Trees to your worlds. When you mine the wood while having a Glass Bottle in your inventory, you will harvest Latex, which is a crafting ingredient for this mod. Also, when you mine the Rubber Wood, you obtain 4 Wood Chips. When you have 9 Wood Chips, you can craft a single Oak Wood Plank.

Latex, combined with Sugar, can craft Chewing Gum which, when eaten, inflicts Night Vision, Saturation, and Speed for a few seconds. Also, you can smelt Latex to obtain Rubber. Rubber, when placed in a circle around a Cobblestone, creates Rubber Floors, which are like carpets yet have Stone properties. You can also smelt these Rubber Floors to obtain Fancy Rubber Floors, which look fancy.

Finally, when you place Rubber with a single Gunpowder, you can craft Tough Rubber. With this, you can craft a full toolset of Rubber stuff in the same fashion as other tools.
