Outside 2

Well as my final outside activity I went and saw mt Math prof's student for one of his classes. They had built hover crafts!! they used leaf blowers and designed the chairs they sat on but they really worked and i was completely mind blown. I wanted to know how it worked so bad so i decided to ask. He said that the two leaf blowers generate enough power if angled correctly at the ground to give a little lift the lift is enough to raise someone off the ground and allow them to float in the air slightly. Then we have someone push and run behind the person floating to get them to move but stopping is a problem because its not like you can slow down to a stop like in a car. but its a concept like it. they Had to manually stop the people after they eased of the gas on the leaf blowers but immediately stopping could have hurt someone.
