A giant inflatable jelly you can walk through and a boba-inspired ball pit land at Westfield Stratford City this weekend, free to visit and stocked with prizes worth up to £100.
Angel Delight is bringing its Bubble Jelly pop-up to Westfield Stratford City’s top floor main walkway from Friday 21 to Sunday 23 August, a three-day, free-to-attend installation built to celebrate the brand’s Bubble Jelly Pots. The centrepiece is a giant inflatable jelly dome that guests can step inside before making their way into a colourful, boba-inspired ball pit next door.
A hidden Golden Ball, and prizes worth up to £100
Beyond the photo opportunity, there’s a proper incentive to dive in. A single Golden Ball is hidden somewhere in the ball pit each day, and anyone who finds it within ten seconds wins a gift card worth between £10 and £100 to spend on family attractions, entertainment or shopping. There are 42 prizes up for grabs daily, though once a day’s allocation is claimed, no more become available until the next day, unclaimed prizes roll over rather than disappearing. It’s one prize per person, participants need to be aged four or over, and under-16s must be accompanied by a parent or guardian, so check the terms and conditions on Angel Delight’s website before you go if you’re planning around it.
There’s a dedicated photo booth set up to capture your moment in the ball pit, with an instant print to take home as a keepsake. On the tasting side, visitors can sample Angel Delight’s Bubble Jelly Pots across four flavours, strawberry jelly with strawberry boba, mango jelly with passionfruit boba, blueberry jelly with raspberry boba, and lemonade jelly with strawberry boba, and there’s also a chance to take home the brand’s classic strawberry and butterscotch dessert mixes while stock lasts.
The London x London Take: this is exactly the kind of free, low-commitment family activity that’s worth building a Stratford trip around rather than going out of your way for on its own, it’s a quick stop next to the shopping you’re probably doing anyway. Sunday’s shorter midday-to-6pm window is the one to watch if you’re planning around nap times or trains home, and with only 42 Golden Ball prizes up for grabs each day, we’d get there closer to opening on Friday or Saturday rather than mid-afternoon if that’s the main draw for you.
