The Big Bangs

In this week's episode, Tim Shaw begins his explosive journey with a bang as he tests out which everyday grocery item can cook up the most pressure on a heated launch pad. Then he attempts a workshop demonstration of how a seemingly solid glass droplet can become a primed and ready grenade in the blink of an eye. Next, he attempts to stun local antique collectors by appearing to turn zinc to gold, before organizing a desert race between four very different propulsion methods.
