Re: Odds and ends

These frames seem to show some segregation, maybe an interval of duel flow in the neck?

Re: Odds and ends

This is the evolution of the flame and color transition all happening in this one run and brief amount of time. From green to orange to a greenish-blue something or other.

Re: Odds and ends

This dog was some sort of lotion or liquid soap dispenser made of very fragile material which cracked easily. Sadly this is all I have of the little barking dog.

Re: Odds and ends

The Pinch bottle wouldn't sustain so a shorter snorkel was tried which brought it around. It was loud and foolishly I wasn't prepared to stop it but having my lighter in hand, quickly and awkwardly put that in the exhaust but it just slowed slightly and then went back to its speedy self until gettin...

Re: Odds and ends

In other news I decided to crack the seal and pour out a very old bottle of Pinch whiskey and try the shape with a simple press fit 3/4 inch piece of aluminum tubing snorkel. It's pretty lively as far as snorkelers go but I haven't gotten it to sustain at full grease, the flame front nifty loud in t...

Re: youtube

Around the 3:47 mark it looks like a brief clockwise circular motion is occurring instead of the typical jam jar torus, and at the neck,
the outflow flame segregating to the right.

Re: youtube

I was watching a show on sea snakes last night and this particular sea snake being of terrestrial origin can't lay it's eggs in water. So it lays them in this underwater cave. The neat thing about the cave was that a fog or cloud was generated when the waves created high and then low pressure varia...

Re: Odds and ends

So I was toying with this jumbo wine bottle and wanted to mention that if you try to rev it up without the copper tube insert there's no hope to get anything other than a strange whistling eddy current whoosh. But unlike 5 gallon jugs that will sometimes cycle up into jam jar mode there's a whistlin...

Re: Odds and ends

If you lived somewhere where there was an ice-covered pond, something like this sleigh wine bottle holder would be cute propelled by a wine bottle snorkeler, albeit briefly whatever time is allowed before the glass self-destructed. Too bad they don't make quartz wine bottles. Or wouldn't it be nice ...

Re: Odds and ends

Something exquisitely easy occurred this evening dinking around with a wine bottle. At first I wound some aluminum tape around a piece of tubing after sticking it down the neck of this wine bottle. But It was roughly flush with where the neck enters the main region of the bottle and I didn't get any...

Re: youtube

I recall probably several years ago pondering that swan vase/decanter he tried, wondering if something like that might be fun to tinker with. Here he has an illustrative demonstration of using too thin of glass. It was fortuitous he was looking toward the camera when it gave way. Model Rocket Engine...

Re: Odds and ends

Well it may not seem like much, but I finally got the perky 1/2 inch diameter snorkel on the 12 ounce paintball tank to sustain for a full grease 5 second run. Instead of the typical 30 ml of methanol in the tank and endless attempts, something around 50 ml was used and the tank maybe held at a slig...
