To use: Easy Mechanics+Int Task to correctly prepare a batch of tools.

Another application of memory plastics. A small (12 x 19 cm, 0.1 mm thick, 5 gm) page of memory plastic is imprinted with the specifications of the tool (a hammer, for example). By placing the page in a container holding a specified quantity of distilled water, the molecules of the page realign themselves and the water according to a specified design, resulting in a complete, usable tool.
The resulting piece will last 1 hour and then dissolve back in an unrecoverable goo.
The life of the tool may be prolonged to 24 hours by applying a pre-set electrical current to the object, and a special spray coating will help stalling decay for a week. After this period, the object will quickly dissolve.
Memory tools are usually produced in "books" of simple mechanical devices, special containers and so on. The final mass of the tool is equal to the mass of the ingredients minus 1%.
