New piston idea

It is a piston but it has three different blocks the base, the Stick, and the two plates one of the plates is a sticky plate and normal not sticky plate like the pistons but the idea is that you would put the base down and then you put the stick on the whole of the base and then you put the rest of it wherever you want but it has to be connected to the first stick but when you are done put the plate on the end of the stick and then when you want it retract it put a lever on the base then the stick and the plate will go in the base but if you want it out turn on the base.
