With DJs and bars on three floors, a silent disco under a real spaceship, live music and a pub quiz, the Science Museum Lates are proving that it's hip to be geeky. This month's offering, open to over-18s only, is all about making, hacking and doing (and probably quite a bit of drinking). Explore electronics, build robots and get creative with new technologies including 3D printing. Workshops include kazoo and maraca making and Lates regulars Punk Science will return to entertain visitors with their science themed comedy antics. Entry is free, as are most of the drop-in activities but book in advance if you want to have a go on the Red Arrows simulator (£10) or experience a flight in the 3D cinema (£3).
