Brainiac is almost univeral awful. I don't watch it anymore, but I did catch the end of the program the other day where they were playing darts with the board supposedly rigged to blow up a caravan. Which it quite clearly wasn't.

They also claimed to blow up the caravan with semtex, which was a complete lie as it was clearly blown up with some sort of fuel/air explosion.

Still they did do the best test ever of non-Newtonian fluids. They had a decent sized swimming pool filled with the stuff and it didn't appear to be faked.
