Any of you guys seen / heard of this before?

The use of helium filled bubbles to test out aerodynamics…
That is cool…particularly since they can actually track a singled out bubbles path !
Much improved over observing full streams of smoke or mixed colored smoke streams.
I use Mr.Bubbles myself… I sit down in front of the car with two 24" box fans behind me. I open the bottle, pull out the magic bubble wand slowly ( this is important because if you pull the wand out too fast you can lose bubleage). Then I take a deeep breath, but not too deep because you really don’t need to blow hard. Then I huff out my exhaled breath thru puckered lips.
lol… and how to you track said bubbles?
