Q.E.D - Season 5 Episode 1 Testing, Testing
6.00 48 minutes Q.E.D. looks at how ordinary things are put through extraordinary tests. It's a world of crashes, bangs-and worse. Tests like 'dropping the lift', 'blowing up the pop bottle', 'turning over the petrol tanker' and 'exploding the custard powder'. Virtually everything made by man is tested. To check that it does what it's supposed to do. To see what happens if it breaks and above all to make sure that it doesn't kill you.
