Greg James attempts the viral 'Cinnamon Bomb' challenge live on air for Comic Relief, attempting to eat a massive spoonful of cinnamon. The stunt spectacularly backfires as the powder explodes everywhere, he can't swallow, cinnamon comes out of his nose, and he ends up spitting into a bin while Union J and Little Mix watch in horrified fascination. If listeners text in £20k, the pop stars will have to do it too.
