Because being an adult is rubbish and all anyone really wants to do is thrash around in a soft play area, a bunch of heroes have opened a pop-up ball pit in Hammersmith.
The pit is free to visit and contains 81,000 balls, which can entertain up to 30 people at one time.
It is the brainchild of creative agency Pearlfisher, who will donate £1 to the charity Right to Play for every person that visits.
They've shunned the traditional multi-coloured balls, instead going for a nice calming, utopian white.
The installation follows a similar one from Turner prize-winning artist Martin Creed last year, who filled a room with white balloons.
