Some spinning bubbles starting at 3:50. Pretty cool bubble art.

Who knew you could do such things with bubbles? Wondering exactly how the large stationary bubble above accommodates the carousel's relative rotation?

I can imagine a bubble-making top with cup-shaped rotor opening upward to hold the soap solution. Rotation would force the solution upward along the cup's inner wall and then outward through properly sized radial holes. The bubbles would then be entrained in the swirling air flow around the rotor.

Such a top might be possible with LEGO, but the rotor would have to be square in plan view.

Oh my!!!  What a great video.  I will have to watch it a few more times and get ready for the warmer weather (it was below zero for the MLK Jr. walk yesterday).
