We investigate Britain's most dangerous household products. Brainiac boffin Jon Tickle tests out DIY spud guns. We nip off down the boozer to see if old wives' tales about drinking are true. Can you juggle whilst being electrocuted? A page three stunna, an opera singer, and a deep-sea diver - who has the biggest lungs? Martial arts v rock and roll - place your bets! Tall v small battle it out at the car wash. And what to do in winter when you can't afford to buy a sledge. Oh yes, another caravan bites the dust.
