I'd like to experiment with using a 2L coke bottle as a pressure vessel

Does anyone know of an adaptor that would let me connect some flexible
pipe (10mm ID say) to the neck of the bottle?

The thread seems to be common for lots of bottles now but I haven't
found a suitable adaptor yet.

Might find something in the spare parts for the Zounds bike air horn.

The MK I had an aluminium bottle to hold the compressed air.
The Mk II had a plastic bottle which looks like a drinks bottle.
ISTR reading of an upgrade to a 2 litre coke bottle.
But I could be wrong.

If any air reservoir bursts, someone could get injured.
Even a Coke bottle.
