Bathtub Bluedart

I thought it would be interesting to see what a bluedart would look like if you launched a fart in the bathtub, lit the methane gas as it broke the surface of the water and capture all of it with high speed cameras. I started with one highspeed camera to test the timing and ended up using two that were parallel to each other and mounted them individually on motorized tracks. Both cameras and tracks were submerged and lowered to the exit. Several attempts were made to get the precise timing so that the cameras would launch at the beginning of the first bubble and travel out of water at exactly the sametime, then continuing upward 8 inches above the waters surface. My well timed assistant Veronica, used a Bic and lit the gas as it exited the water. Eureka! We filmed 25 seconds of underwater bubble paradise, that I still use as a Sscreensaver today. An additional 25 seconds was fillmed out of water capturing the first bubble pushing its way through the waters to the awaiting flame. It egnited a myriad of blue colors, each bubble liting the next as it exited.

It is still my favorite highspeed film to date.

I was surprised by the shear size of the flame that was created as my Bathtub Bluedart exited the water nearly taking my eyebrow off.
