Spray bottles are an extremely useful type of machine and an excellent demonstration of basic plumbing principles.
A spray-bottle head is made up of only a few parts.
It has a trigger lever, which activates a small pump.
This pump is attached to a plastic tube that draws cleaning fluid from the bottom of the reservoir.
The pump forces this liquid down a narrow barrel and out a small hole at the gun’s muzzle.
The hole, or nozzle, serves to focus the flowing liquid so that it forms a concentrated stream.
