Video footage of scientists demonstrating the potential explosive power of devices used in the alleged 21 July attacks has been seen in court - Woolwich Crown Court heard evidence from explosives expert Clifford Todd, whose team carried out the mock blasts. He said they blew up replicas of the devices alleged to have been used by the defendants, containing a mix of chapatti flour and hydrogen peroxide. Six defendants deny conspiracy to murder and to cause explosions. Quite the blast indeed. Many innocent people would have been killed and injured, and of course the accused are pleading not guilty in spite of several eyewitness accounts and cctv footage of them buying the components and trying to escape once the bombs failed to detonate as intended.
