Science Machine

The Science Machine is a Science structure item in-game. It costs 1 Gold Nugget, 4 Logs and 4 Rocks to craft. The Science Machine is used to prototype items, effectively unlocking the items so the player can craft them at any time with the materials required.

The Science Machine is used to unlock tier 1 items, and the Alchemy Engine is used to unlock tier 1 and tier 2 items, making the Alchemy Engine the higher level Prototyping machine.

Trivia

 * In the early beta of Don't Starve the game used a "Research points" system instead of prototyping.
