1) HAVE A MASSIVE WATER FIGHT
Whatever you’re meant to be doing on Sunday, we suggest you cancel and head over to the Barefoot Refresh Summer Cool Down. Why? Because it’s shaping up to be a wicked water party, complete with giant foam pit, coloured water-shooters, cooling CO2 jets and glitter body art. Need we say more? Dalston Roof Park, Print House, 18-22 Ashwin St, E8 3DL. Enter the ticket ballot here. Sun Jul 19. Free.
2) GO ON A MONSTER SLEEPOVER
What could make sleepovers even better? Booze, obviously! And live music. And a monster-movie marathon. And stand-up comedy. And hulking great dinosaur skeletons to sleep under. Welcome to Dino Snores, a sleepover worth waiting 65 million years for. Natural History Museum, Cromwell Rd, SW7 5BD. www.nhm.ac.uk. Jul 24 and Aug 21. £180.
3) RIDE A GIANT WATER SLIDE
A huge inflatable water slide running down the hill in Alexandra Palace Park? Surely this is too good to be true? Nope, it really is a thing. The 150-metre wonder will be set up for Ally Pally’s Summer Festival on July 25. All proceeds go to Cancer Research UK, so you can get wet and be worthy at the same time. Alexandra Palace Way, N22 7AY. Jul 25. £20 for two slides.
4) DRESS FANCIFULLY AT A PARTY
Outlandish costumes. Colourful decorations. Lots of overexcited souls wreaking havoc… It might sound like your eighth birthday, but it is in fact a typical night laid on by deranged party pioneers Rumpus. They’re unleashing their delightfully juvenile brand of hedonism on the capital once again this autumn, taking over The Coronet for a fancy dress night that’s sure to bring out the child (and devil) in you. 28 New Kent Rd, SE1 6TJ. Oct 2. Price tbc.
5) PLAY YOUR FAVOURITE SUPERHERO
Walking around dressed as Thor would normally result in mockery and possibly getting beaten up. But at Comic Con you can live out your youthful fantasies freely while proudly mingling with hundreds of other heroically attired cosplay fanatics. Bring a change of clothes for the journey home. Or risk it, Oh mighty Thor. ExCel London, Royal Victoria Dock, 1 Western Gateway, E16 1XL. Oct 23 25. £15-£50.
