      Small plastic engines that run from compressed air. Come in 3 sorts, 2 with propellers and one with a gearbox. Cheap and just waiting for someone to think up a lower school class experiment. One student tried measuring the power output compared to the number of pumps. The one with the blue bottle goes for the longest time.

      These motors used to be available from MUTR but no longer appear to be. Anyone know of another supplier or similar product?

      Air Motors
      Air powered motors are used in a variety of toys and models, but up until now it has been impossible to obtain them as separate power units (other than relatively expensive CO2 gas power units for model aircraft. Mutr now offer two types each with an integral high pressure reservoir. A special pump is available, but ordinary cycle pumps with car valve type termination can be used with an adaptor.
