Hi Mike.
Nothing to do with Clit Bang.
The hot air/steam cooled down and caused the vacuum.

I don't think so.

I just ran a test with hot water only, and also with washing up liquid to
give a foam (which I've done many times before with the same bottle.

The only effect is a slight increase in pressure as the air inside is
heated by the shake with hot liquid.

The cillit bang effect (prolly other "oxy" cleaners would be similar) was
instant and really dramatic, the bottle was virtually flattened.
