Wonder what the barometer telltale got to .....
I'm impressed it's still afloat & didn't catch fire, but I suspect that the % air gas mix was deliberately planned for bang rather than burn.
Some technical info on the relevant %'s for - nowt, bang, fire & nowt again would be helpfull, cos I think that it is around 5% gas-air that the problem is worst.
It'll make a nice project for somebody
Seriously, how are you going to dispose of all that fibreglass?
Ta, Glynn, surprised to see Carbon Monoxide in that list with a 12-75% explosive/flammable range. I thought CO, like CO2 was non-flammable & put flames out.
Will you be doing an article on the insurers response?
Was this recorded on video by any chance. If so can you post it later?
Hey Iain, note to self...
Don't let a bunch of lashed-up 12fter sailers sleep on your boat after a curry night...
and if you do, hide the matches!
This reminds me of a demonstration we had in the science lab in school about 50 years ago.
The science master had an old treacle tin with a small hole in the bottom, and one in the lid. The 2 holes were covered with a bit of tape, then with the lid off, the tin was held upside down over an unlit bunsen burner, which filled the tin with gas. The gas was turned off and the lid put back on the tin while it was still upside down. Then the tin was turned up the right way and placed on to a tripod stand. the tapes were removed, and the gas coming out of the top hole was lit. As gas came out the top and was burnt, air went in the bottom hole. Nothing happened for a few moments, until there was enough air in the tin to make an explosive mixture - then BANG!, and the lid flew off up into the beams of the old high roofed classroom, where it rattled about a bit before gravity took over and it clattered to the floor. The tin also went shooting off somewhere, but fortunately missed all the 20 or so boys looking on in awe! It gave us a few ideas about repeating the experiment, which I must admit I did outside our back door, with equally spectacular results! !
Can you imagine anything like this being allowed today?
Shame really, as boys enjoy a good explosion!
