Battle of the bats - we ask "Which is Britain's best sport?." Does time really fly when you're having fun? Thank God for science - we say cheerio to another caravan. Will a blackbox flight recorder survive an acid bath? Brainiac boffin Jon Tickle goes ballistic with the help of some fruit and veg. Which socks are the slipperiest? Tina Tuner + her Bunsen Burner + TNT = A recipe for disaster. We go gardening the lazy man's way. And your last chance to vote and win with Explosive of the week.
