Brainiac not so brainy?

At which point does flash in the sake of science mean throwing out the science? As in the following clip:

Pretty cool? Yep! But accurate...? The Mythbusters tested it, and the results weren't quite as spectacular... so this means that the Brianiac crew didn't quite follow the science... or did they? This discussion is interesting, but does raise the point: to make science fun, does science have to be sacrificed?
