The Science Museum's monthly late opening rolls round again tonight. From 6.45pm till 10pm you can roam those magnificently decked halls learning about science and technology with a glass of Chardonnay in your hand. Entrance is free.
As always, there's a varied programme of events (PDF). The main highlight has to be the jovial Richard Wiseman exploring human fascination with the paranormal. But you can also sit on a Chair of Doom (!), take part in a science pub quiz, hurl Barbie dolls from catapults (just don't call them angry birds), try some speed dating, and generally mingle like a random particulate in an ideal gas.
