Jump In! promises oodles of ball pool fun for up to 30 grown-ups at a time, and has been created in Hammersmith by creative agency Pearlfisher as a soothing art installation. It’s open for the next fortnight, and admission is free.

And the really good news is that as you romp around you’ll also be helping others to do the same. Because for every visitor Pearlfisher is donating £1 to the charity Right to Play, which helps to counter the effects of poverty and conflict on children by teaching them sport and games.

No kiddies in this pool though (although you may wish to make yours watch jealously from the side). In fact it’s so adult that the balls aren’t even multi-coloured – they’re all a nice, calming white. (All right, all right. The picture’s got coloured balls – we know!)

The installation follows a similar one last year from Turner Prize-winning artist Martin Creed, who filled a room with white balloons.

Jump In! is at Pearlfisher Gallery, 50 Brook Green, W6 7BJ, until February 13, and is open from 10am-5pm, Monday to Friday. Email jumpin@pearlfisher.com to reserve your place.
