There must be a valve moulded into the base of each glass.

[DTCwordfan]

dont know - a one way valve in the base of the 'glass'?

That's good. If you look you can see the disc device in the bottom of the glass just before it starts filling.

[ummmm]

What a good idea.

But beer from plastic glasses? Ugh!

[ummmm]

No choice at festivals....

[NazNomad]

As the comments on those links say ... Who'd want to drink that after his fingers had been all over the rim of the glass?

[ummmm]

Haha Naz...I think that would be the last thing on festival goers minds. Have you seen the toilets :-((

[NazNomad]

Fortunately, no.

[ChuckFickens]

I was thinking that too, very bad barmanship (is that a word)

[NazNomad]

Yes it is ... I'd have been sacked for handling clean glasses like that.

[ummmm]

Well if you had a barman touching the rim of your glass is the least of your worries...

Yay..bring on Glasto 2011 :-))

[ChuckFickens]

Me too (not to mention the grief I'd have got from the regulars)
