Great Yarmouth is all at sea with series of maritime themed events, while Norwich Castle Museum promises a firey finale to a special late night opening.
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.
In Great Yarmouth the nocturnal happenings have a maritime flavour. Chiming with the current Titanic exhibition, Time and Tide Museum, on Blackfriars Road, will be turned into RMS Time and Tide on May 19 (6pm-10pm, free entry), with a nod to the Edwardian passenger liners of the past. Will you spot a famous billionaire?
Send a telegraph with our Marconi machine and dust off your table manners with some first class dining lessons. Or maybe you will venture down to third class to where the real party is?
There is a mutiny at the Tolhouse Museum on May 19 (6pm-10pm, entry free). It has been taken over by its crew and the captain is locked in the cells, can you free him before his men find out? Or will you be enticed by the crew to their side, with their cannons and weapons?
