As the merry-go-round revolves slowly, the solution washes over the cancer tissue, which grows vigorously just as if it were in a living body. Drugs can be tested against it simply by adding them to the solution...

Their inside works are very like the jets', but instead of putting all their propulsive energy into a blast of hot gas shot out the tailpipe, they extract some of it by means of a turbine set in the blast and use it to drive a conventional propeller. This compromise gives turboprops some advantage. They are simpler and lighter than piston engines, and they burn cheap, nonexplosive kerosene instead of high-octane gas.
