Slow puffer 2 is a puffer that was found by David Bell on August 21, 1993. It consists of a blinker puffer 1 with a p18 "house" blinker fuse attached to the back of it to suppress the blinkers and two MWSS's to give rebirth to said fuse (and leave the bi-blocks in the process). Its name comes from the fact that it creates debris very slowly, only creating a single bi-block every 240 generations.
Rake
A convoy of 5 assorted spaceships can turn the bi-blocks produced by this puffer into gliders, completing a period 240 forward rake.

Glider synthesis
A 23-glider synthesis of a period-240 spaceship[1] involving this puffer being capped with a middleweight spaceship was completed on 7 March 2022.[2] The middleweight spaceship can be removed to yield a 20-glider synthesis of the puffer. The synthesis was reduced by two gliders the next day.[3]
