They can't promise that exhibits will comes alive but the Museums at Night initiative will this weekend see museums stay open longer to welcome visitors after hours.

Norwich Castle is offering a chance to venture into the unexpected on May 20 (5pm-9.30pm, free entry). In the miniature world of the Small Stories exhibition you will be able to enjoy the fun with the Foolhardy wonderland characters. Choose your ingredients and concoct a 'drink me - shrink me' potion to take home, or journey into another world with our story teller.

There will be a magic entertainer and you will be able to help him perfect his tricks and join stonemasons and apprentices from the Guild of St Stephen and St George as they reveal their own tricks of the eye.

Pick up a prop and examine museum stuff in a different way, or do the maths and calculate how much you need to grow or shrink to fit in the viewfinder. The night turn will end with a spectacular Fiery Finale.
