I Didn't Know That

Our duo examine the pros and cons of plastic including Bakelite, celluloid and Kevlar used in anti-stab material. Then there's Teflon, this slippy plastic isn't just used in frying pans, it's also used for sledges, so the lads head to a ski slope to test its effectiveness. Using his angle grinder, Jonny attempts to see if it's true that golf balls contain elastic bands. Meanwhile, on an investigation into the history of the humble brick, Richard meets a brickie who can lay 350 bricks per hour and attempts the sport of brick throwing. Finally, we visit a newspaper printing plant too see how 4.4 million papers are rolled off the press each week.
