Put a gang of overactive kids in a dimly lit room, give them a paintball and permission to throw it around at random and you can guarantee they'll love it.
It's hard to imagine a group of children not having fun at Paintball Headquarters - unless they are on the receiving end of too many paintballs which, according to several of our all-girl paintballing party, sting if they hit certain places.
But what's a little pain in return for firing gelatin-coated balls of coloured water at your friends?
The Paintball Headquarters is one of those places most parents in Hong Kong don't know exists until their children reach a certain age or height (eight years or 130cm tall) and the invitation for the birthday paintball sessions arrives.
For overprotective parents, the waiver they sign for under 18s may be daunting, especially as it warns that playing paintball or misusing the equipment puts your child at risk of 'partial/or total paralysis, eye injury, blindness, death ... or other ailment that could cause serious disability'.
However, the staff take safety seriously and insist on goggles being worn at all times while on the course - an air-conditioned room of hideouts and obstacles.
