One question a lot of people have asked about the 7/7 bombings is, could homemade explosives made from hydrogen peroxide and black pepper have caused the observed damage, or must the explosives have been, as early reports claimed, "of military origin"?[1] [2] [3]

This is something I've wanted the MythBusters or someone to test for a while (blowing shit up is, after all, the MythBusters' specialty!). Well apparently the BBC are going to finally settle the debate. Remember that 9/11 conspiracy road trip program? Well this year they're airing one about 7/7. In the video above, Paul Joseph Watson interviews one of the participants of the upcoming program. Apparently one of the things the BBC did was blow up a bus in a quarry using the ingredients the bombers allegedly used. Should be interesting.
