Rotating Cartesian diver

Let's take a look!

What type of experiment is this?

Experimental procedure and explanation:

• We apply the previously published Cartesian diver to develop a floater sinker that floats and sinks while rotating.
• The rotation is generated by attaching blades In the same way as the previous Cartesian diver, this is attained using a dropper and a nut (weight). Additionally, a blade is placed between the two nuts used as weights.
• The blade is cut from a thin plastic case.
• The blade rotates when the flow hits it, and similar to a wind turbine, the floater also rotates.
• A rotor with blades attached around its axis is referred to as a rotor blade.
• This experimental video was produced with the support of JSPS Grant-in-Aid for Scientific Research 18K03956.
