All this reminds me that Howard Hughes flew round the world in a Lockheed Electra packed with ping pong balls in 1938

Thanks RobWheatley - Ok time for scatty ideas.
You are in the middle of the atlantic and sinking (heavy weather and broken windows/washboards are allowing boat to flood) could you save yourself/boat and provide a better liferaft by filling bin liners with expanding foam (say 36 cans of expanding foam & 100 bin liners on board for such an emergency) and say filling up the front and aft cabins and heads if necessary leaving a waterlogged boat with a habitable saloon area as a liferaft but it could be pumped out manually when conditions moderate!
Apologies for thread drift

Nope - if you spray builder's spandy-foam into bin-bags it doesn't work. Just deflates into a brown slimy liquid. I tried to use it this way to mould perfectly-shaped blocks around Kindred Spirit's fuel tank, and it failed miserably.
The two-part liquid foams may work, I haven't tried.

Why?
I had 2 cans of expanding foam (cheapest one from screwfix) in a carrier bag in back of new Audi estate car and loading in old boiler for scrap we accidently punctured one of the cans. it went off great guns - fortunately my friend was quicker thinking than me and picked up carrier bag and threw it in the road before it damaged the back of the estate. Before we left the site a great big block of foam had inflated the carrier bag and extended to outside the bag.

I'd pay, to watch a few of those go off!
It's a nice little idea but I can believe it's not reliable as an emergency buoyancy solution...let alone the rather comic Harold Lloyd image of a man rushing about the cabin of a sinking ship, squirting air into bin-bags.

At some £6 a can I did pay as the carrier bag had another undamaged can in the bottom when I threw the large mess into a skip!

This takes me back. Years ago, as a nipper, my friends Dad was refurbishing an old motorboat. He brought home a tin of expanding foam and activator and demonstrated a small amount in a polystyrene cup and added the activator. It made a fantastic mushroom shape (we made a few and painted them as mushrooms) as it foamed up and overflowed. Later he filled in spaces behind bulkheads with it by pouring in the agent and later the reactor. My friend and I got to chop off the flash that flowed out of holes he had drilled for this purpose.

Very interesting, could you give an example please?

Your comment suggests a little sceptism. However, it is quite feasible
I have seen a brand new mini transat being launched then someone spent the next couple of days fitting large blocks of foam inside. Whether this was to keep the boat afloat or the helm warm i know not. But there was sn awfull lot of foam inside that boat when they finished
