Which is faster - a motorbike, a golf ball, or a firework? Brainiac boffin Jon Tickle goes undercover with X-Ray specs. Vacuum cleaning - does it really suck? Brainiacs get sloshed checking out hangover cures. We do more bad things with a microwave oven. Tina Turner and her Bunsen burner are back with another big bang. It's slime time for Dr Bunhead!
