make sure you...

Donate... Some blood in exchange for a free ticket to the Museum of the Moving Image's Hammer Horror exhibition. Vampires and ghastly ghouls will be on hand as a reminder that there are worse ways to lose your blood. MOMI is holding a Vampire Valentine's evening on 14 Feb. Sink your fangs into a Bloody Mary before a visit to the exhibition, and then on to the lesbian horror flick The Vampire Lovers, showing at the NFT. Blood donations gratefully received between 11am-5pm, at a mobile donor unit outside the MOMI.

See... something with the young'uns. Sherman Theatre presents a touring show of Under The Bed, a comedy for 4-6 year olds. Mo and Jo cannot get to sleep, and they think there is something scary under the bed. With the help of a hot water bottle and a magic bed, Jo and Mo are taken around the world to find a safe place to sleep. Under The Bed explores the power of imagination to deal with children's nighttime anxieties.
