Three things you won't want to miss in London this Thursday

1. Back by popular demand, Festibowl will once again take over Finsbury Square with DJs, food, cocktails and – yep – lawn bowls. Assemble an A-team of four players, and book your spot in advance. If you have the energy, you can head to the official after-party at The London Shuffle Club in Shoreditch. Keep on the grass. 

2. Movie merch collectors: try not to drool at the free 'Prop Store Film Memorabilia Exhibition', where 600 props – including Thor’s hammer and Marty McFly’s light-up Nike sneakers from ‘Back to the Future Part II’ – will be on display. Find them all at the BFI Imax until September 26. 

3. Can Graphic Design Save Your Life?, find out at Wellcome Collection's new exhibition, which explores the relationship between graphic design through a collection of retro pill packets, neon pharmacy signs and cautionary posters.
