Reanimation is a reaction performed by a convoy of spaceships (or other moving objects) which converts a common stationary object into a glider without harming the convoy. This provides one way for signals that have been frozen in place by some previous reaction to be released for use.

Simple reactions using period 4 c/2 spaceships have been found for reanimating a block, boat, beehive, ship, loaf, bi-block, or toad. The most interesting of these is for a beehive since it seems to require an unusual p4 spaceship:

Reanimation of a loaf is used many times in the Caterloopillar. It is also used in the Caterpillar as part of its catch and throw mechanism. Finally, reanimation can produce rakes from some puffers. See stop and restart for a similar idea that applies to Herschel conduits and other signal circuitry.

There are small objects which have no known reanimation reactions using c/2 ships other than the brute force method of hitting them with the output of rakes.
