The Smallest Rocket Thrusters - How Can Tiny Rocket Engines Work

I previously talked about the largest rocket engines, but it turns out there's a lot of interesting small rocket engine designs, and the smallest designs possible heavily depend on the type of engine cycle used.
Small engines enable smaller spacecraft which means lower launch costs without giving up capabilities which might have been previously reserved for full size spacecraft.
