Bubble Rings

Bubble Ring Day. It was so hot in the desert today all we could do was swim in the pool. Good thing I had my trusty uber-unterwasser-oring-foto-kamera along. We blew off some fine bubble rings and had fun watching them wobble and grow as they floated up through the water. These bubble rings are actually stable toroidal air pockets that usually maintain their delicate shapes all the way to the surface (if left to ascend undisturbed). I was pretty lightheaded after spending 30 minutes repeatedly holding my breath on the bottom of the pool making these bubble rings, so I did it for another 20 minutes and got super lightheaded. It was way more funnerer than hyperventilating into a paper bag. Ah, good times.
