It’s that time of the month once again when the Science Museum opens its doors long into the night. Well, up to 10pm anyhow. As usual, you can expect live entertainment, plenty of booze and no children to get in the way. Tonight’s event is food-themed, including the chance to make an instrument out of a vegetable. Those who select spinach might be at a disadvantage. Doors open at 6.45pm and entrance is free.
