I still remember that I watched an American TV play called Noah's Ark in my childhood. I envied the free soar of the flight in it. Recently, Canadian engineers have turned this dream into reality, and all of this is completed on the water.
This thing called Jetley-Flyer adopts a powerful engine to draw water downward through the water hose connected with the engine to generate power, and then the operator is pushed up into the air and forward by water jet. It can push people 30 meters high into the sky, and its maximum speed reaches 35 kilometers per hour. It must be very cool to ride on it, but stimulating things have to pay money as a price, and the current price of this device needs 110000 pounds.
