Yes, many jokes can be made at the expense of Dyson , the UK-based manufacturer of odd-looking vacuums and fans, and its employees. But those hard-working engineers clearly know a thing or two about recombining common parts to find innovative solutions to every day problems.As hard as they work, they also apparently play hard.

It's like drag racing for geeks and, true to Dyson form, some of the entrants don't look like anything resembling a car. Scroll down to watch Dyson's engineers cut loose and compete for the quickest times.
