Scottish glasses fill from the bottom while I fill from top

If the river were lager and I were a duck, I’d buy a Trufill concept device designed for stadiums that can fill ten pints of beer in ten seconds and drink it all up. This amazing new concept uses magic and space technology to fill up glasses from the bottom up. How? I don’t know. No one knows. All we know is that we have to go visit FoodBev next week and if this amazing system is true my drink will be on so hard that it will be difficult for me to post from Monday to Friday anymore.
