A Caledonian University student claims he has made an important breakthrough in how to pour "the perfect pint" during Euro 2004.
David said his device pours "the perfect pint"
David Stevenson, from Helensburgh, said his device is "fool-proof" and enables football fans to watch games without worrying about pouring problems.
The Homer beer pourer was one of 60 designs on display during the university's Product Design Week.
Students were asked to create a product "from the inside, out".
Mr Stevenson, 22, said his device allows football fans to watch replays of crucial incidents during games, without worrying about "a big head" in the glass.
He said: "I'm not sure about the exact scientific reason why it works but it does.
"I've had to go through a few models before getting it right.
"There has been plenty of heartache along the way with cans of beer falling down the plughole but I managed to get it right eventually."
The device works with 440ml cans and a pint glass. The glass is attached to the clip and the pourer is nudged to begin pouring the drink.
As the liquid is transferred, the spring slows the rate to achieve "the perfect pint".
The students working towards their BA (Hons) in Product Design were briefed to create a product and think about every element of design.
Lecturer Fred Birse, from the university's School of Engineering, Science and Design, said he was delighted with the response.
"We wanted the product design course to be more hands-on, so that the students actually create a project that works, rather than something that looks good on paper but fails in reality," he said.
"Fitting in with Glasgow Caledonian's 2010 vision, we hope to stimulate budding entrepreneurs who can now design, make and sell their own ideas."
