You've been pouring your Guinness all wrong

Ordering a Guinness on drafts takes longer than most other beers. Part of the reason is the gas used to carbonate it: nitrogen. William Lee, a professor of Industrial Mathematics at the University of Huddersfield, in a study funded by the Science Foundation Ireland, discovered that the specially designed Guinness pint glass causes the bubbles to sink and increase the wait time for the beer to settle. Lee believes something closer to a giant martini glass would work better.
