A water bottle propeller is a straightforward machine that may be made out of just a few fundamental supplies. It’s a good way to be taught concerning the rules of aerodynamics and the way propellers work. With just a few easy steps, you may create a water bottle propeller that may fly by the air.
There are various other ways to make a water bottle propeller. One widespread methodology is to make use of a plastic water bottle, a pair of scissors, and a stick. First, minimize the underside off of the water bottle. Then, minimize 4 slits into the edges of the bottle, about 1 inch from the underside. Subsequent, insert the stick into the underside of the bottle, and safe it with tape. Lastly, bend the 4 slits outward to create the propeller blades.
