Disappearing Propeller Boats video
The charming “Science on the Move” video below, shows a series of ‘Dippies” in all their glory, including insights on the operation of their sometimes cantankerous engines and disappearing prop mechanism. (Please be patient. The video doesn’t really begin until the 33rd second.) Enjoy!
