Alright. I guess this list has finally come through as I knew you could.
Here's the story, less blow-up dolls.
Our younger daughter (23) is a mechanical engineer and foodie interested in
this NASA project -
Among many requirements is a proposal for a research project to keep the
participant busy in the four months of confinement in Hawaii. Our daughter
is considering several possibilities, among which is an ultra-compact
emergency shelter for a spacesuit-clad Mars astronaut caught out for some
reason. Various gas-filled structures come to mind, including free-standing
Mylar domes and gas-filled Mylar tubes acting as supporting "rods" for Mylar
tents. The latter has the advantage of reparability and easy spares. Those
pop-up tents with memory-metal rods are another possibility.
I don't yet know what she has proposed or how easy it will be to modify that
proposal later. But meanwhile, I am doing some grunt work looking for
supplies that might be useful. I have found fittings used on blow-up kites
are pretty cool, but they are $20 each. 10,000 vinyl valves are a bit much,
but cutting them off of cheap beach balls is a great idea and well in
keeping with her budget.
So you see. the query is actually pretty interesting after all. Thanks for
