Elsewhere, there's gay and lesbian speed dating and a talk about Pedro Almodóvar’s film The Skin I Live.
The main lecture theatre has a talk on the science of sex, promising to answer such questions as 'why we fancy the people we do', and 'why love exists'. You mean they have a surgeon today that can change the brain from thinking itself one sex to the other? To throw those born with an intersex condition into the same venue as those under the transgender/transvestite construct is ignorance and not an anatomical truth.
Queues can stretch round the block close to opening time.
Simply turn up, walk in for free, grab a glass of wine and enjoy the world-beating displays and live entertainment without the normal ruckus of children running about.
Long-time Science Museum Lates mainstays such as the silent disco, speed dating and the science quiz will also take place.
A full events programme for this evening can be found here (PDF).
Tonight's Late is themed around the future, looking ahead to what we might expect from science, engineering and technology.
