Pipsquirter 2 is a period7 pipsquirter discovered by Noam Elkies in August, 1999.^{[1]} Because of its easilyaccessible domino spark, it is useful in the construction of larger patterns such as the p49 glider shuttle, the first known period 49 oscillator.
As a reflector
Pipsquirter 2 is most useful because of its ability to act as a 90degree glider reflector (see p7 bouncer) when it is combined with a block, boat and eater 1. It takes 9 generations to recover from the impact, and the input path (in green) and output path (in red) of the glider are shown below. This reaction is the basis of the p49 glider shuttle and the bricklayer.
A version of the pipsquirter stator with slightly higher clearance is shown in the p7 bouncer article.
