The only problem with bubbles is that they don't persist nearly long enough.

This invention requires some kind of gun, which accepts a large capacity cartrige full of extremely thin (biodegradable) stretchy balloons. When I say balloons, I mean minature ones that only inflate to about the size of a golf ball--ballubbles. There would be another cartige filled with helium connected to the gun.

You would pull the trigger and inflate a ballubble out the end (somehow autosealing it <--I haven't worked this part out yet) as another one is auto loaded. It would need to sustain a fairly rapid rate of fire.

Check them out bouncing off of the underside of the surface of the water at the end of the video. [2 fries shy of a happy meal, Aug 06 2014]

This I would buy.

Is it possible to produce a toroidal soap bubble?

I know about toroidal bubbles underwater, and toroidal vortices in air. But can you wrap a toroidal air vortex in a soap film to create a fast-moving doughnut bubble?

I like it.
The answer to your toroid soap bubble question is yes. but it doesn't last long. [link]

I would like to see the same attempted in micro-gravity though.

Ah, but that is a static torus. I'm thinking of a moving toroidal bubble that behaves like a smoke- ring with a skin on it. The movement is what should give it stability.

//I would like to see the same attempted in micro-gravity though.// I don't think gravity is the problem. Just add motion.

True, constant airflow through the middle as the bubble is formed would begin rotation and keep its shape. Bernouli should take over from that point on.
In micro gravity the surface tension would take on whole other properties though.
I love watching film and flame experiments in space.

Hope to get there someday before I croak.
Can you imagine weightless old age homes?
Has anyone posted that yet.

It should be possible yes. Depending on the viscosity of the oil used to create the skin there is a fairly new product on the market which should work in liquids thicker than water.
