Russell shouts at the candle
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Russell initially tried to blow out the candle by attaching a vacuum cleaner to a drainpipe, before resorting to blowing through the drainpipe himself, and eventually shouting through it to get the candle to go out. He blew out the candle from 2.86 metres away.
