Wotsit face

Equipment: Shaving foam, Wotsits, towels if you're feeling nice.

Get players into teams with one leader in each team. The leader gets shaving foam wiped all over their face and stands a fixed distance away from their team. For a fixed amount of time, the teams try and throw as many Wotsits as possible onto the face of their leader. The winning team is the team with the most Wotsits that stick.

You might want to line the floor with bin bags if you're worried about making a mess.
