The "Throw the Sponge at a Teacher" game proved to be very popular at a Burnley primary school's summer fair.
The event was held at St Augustine's RC Primary School and raised more than £1,100 for school funds.
There was a variety of stalls and year sixes promoted their Fiver Challenge businesses - where they try to turn £5 into as much as they can by making smoothies, a lucky dip, selling chocolate and many more inspiring ideas.
Headteacher Sinead Colbeck said: "It was a great hour.
"The sun was out, there was plenty of fun and there was also a raffle with staff and parents volunteering."
