A plunger pump is a type of positive displacement pump where the high-pressure seal is stationary and a smooth cylindrical plunger slides through the seal. This makes them different from piston pumps and allows them to be used at higher pressures. This type of pump is often used to transfer municipal and industrial sewage.

Current problem: It is frustrating to have to buy new headphones because they keep breaking.
Major idea: Put spandex in between the plastic and the actual wire.
S-substitute  water proof spandex for the plastic.
C-combine the spandex and the wire.
A-adapt the wire to be thicker
M-magnify the connection in the wire.
M-modify the jack.
P-put the spandex in between the plastic and the actual wire.
E-eliminate the plastic completely.
