Re: Bits of foil
actually, escaping air through the hole would have enough oxygen in it to oxidize most materials that they'd make spacecraft out of, such as aluminum or titanium, both of which rapidly form a protective oxide coating when exposed to O2 in air...
[hence welding aluminum or titanium is extremely difficult, compare to other materials, because of the oxidation and thermal properties and other such thing]
