To sum up, it is a very interesting creation. However, we faced not only the mechanical difficulties but also, the factor water make it even more difficult for us to make it and achieve its good function. Fortunately, our structure with the number 0151 worked efficiently making us very happy and making it one of our favourite vehicles. We hope to make more things that can be used in the sea in the future.

Showing, once again, our weakness in odd vehicles, this time we decided to make an electrical scooter for the water. First, we took an old pvc tube with approximately 20cm diameter. Then, using the lathe, we made threads in the two edges of the tube as well as we processed its outer surface in order to have a nice, smooth finishing. At the one edge of the tube, where we made the thread, we screwed an aluminum piece taken by an old, destroyed aluminum bottle. This part is the basis for the motor that we added later. The motor was taken by an old hover board.

On the motor, we added a stainless steel axis, on which we created the entry for the propeller, which will urge us to move in the water. Afterwards, to avoid the contact between the motor and the water, we added a piece of aluminum, in which the propeller axis passes through. Between this piece of aluminum and the propeller axis, there are two bearings, which help the axis to spin smoothly, and two seals that prevent the water to enter the motor.

On this latter piece of aluminum, we added the protective part of the propeller, which is a piece that prevents the contact between the user and the propeller in order to be kept safe.
Regarding the frontal part of the vehicle, we added an acrylic, transparent dome taken by an old pool filter. This part is removable when it is needed to insert batteries and activate the scooter. Additionally, at about during the middle of the making, we placed two handles that the user holds during driving. Next to the right handle, the throttle for the motor is placed, which sets the speed that the user wants to have.
