Why does beer foam stick to a clean glass?

Hi Scientists of Cambridge!

I was wondering why exactly beer foam residue supposedly sticks to the glass while the beer is consumed only when the glass is clean?

Surely glass has imperfections anyway, so it should stick no matter what.

Regards,

David Toms, Birmingham.

What do you think?
