The wonderful thing about table tennis is that pretty much any Tom, Dick or Paul Drinkhall (he's currently the UK's top player, by the way) can pick up a bat and ball and start playing.
The English Sports Council (aka Sport England) is well aware of this, and so this summer is once again offering everyone the chance to play the game for free at hundreds of outdoor locations across the capital.
The initiative, called Ping!, is now in its third year, and this time around, with the Olympics about to kick off, is set to be more popular than ever.
It's perfectly simple – if you happen to stumble across one of the many tables dotted about the city (see map for precise locations), simply grab a bat, ball and friend (or stranger off the street) and start knocking up. Ability isn't important, just enjoy yourself.
Scheduled activities such as masterclasses and tournaments will also be taking place as part of Ping!
The aim is to get as many people as possible across the whole of the UK playing – to bring about a sense of community spirit and get more people playing sport on the run up to the Olympics," it says on Ping'swebsite.
Look out for tables at places like the British Library, Canary Wharf, London Live sites, Portobello Market, the Roundhouse, Soho Square and Westfield Shopping Centre.
Ping! is also operating in other UK cities, including Bristol, Liverpool, Birmingham, Brighton and Sheffield.
"Ping! has proved one of our most successful sports participation projects, attracting over 150,000 participants to date," says Sport England's chief executive, Jennie Price. "Moreover, our Active People Survey shows that once people start playing they don't want to stop."
Indeed, according to Sport England, table tennis is one of the fastest growing sports in the country. An impressive 135 people now play table tennis at least once a week – that's almost 50,000 more people than last year.
So if you see a table on your travels, be brave, step forward and enjoy some bat-and-ball-based fun.
