Paris Balloon-Homes Are Gas-Proof (Aug, 1935)

Paris Balloon-Homes Are Gas-Proof
REASONING that if balloon silk can hold gases, it can likewise keep gases out, Parisians are building balloon houses—-grim shoe-like affairs which provide safety from much-feared gas attacks.
Entire families will find refuge in each of the inflated structures. Fresh air would be pumped in through a filter which neutralizes poisonous gases, just as do filters on gas masks. Frames of wire hold the balloon silk in position when the air pump is not operating.
