Grantham is gearing up for tomorrow's spectacular finale of the town's highly-successful Sir Isaac Newton-inspired Gravity Fields festival.
The Transformation of the Town will feature a whole host of family entertainment including light shows, fire sculptures and aerial performers from 7pm until 9.30pm.
Hundreds – if not thousands - of people from near and far are expected to flock to Grantham town centre to enjoy the festivities, supported by South Kesteven District Council.
Cirque Bijou, involved in the opening ceremony for London 2012 Olympics, will be performing a new commission in St Peter's Hill exploring and celebrating Newton's work examining the solar system
A huge sun will shine down from Grantham Guildhall with celestial imagery shot from the Hubble telescope projected onto it.
In an extraordinary aerial spectacular that grows and develops during the evening visitors will see Newton studying the stars and night sky – with planets, fiery objects and aerialists. The show will reach its climax at 9.35pm.
Also in St Peter's Hill, Grantham Dramatic Society will be performing a Newton-inspired show near the Isaac Newton statue - which will be illuminated for the event.
Meanwhile, leading UK pyrotechnics company The World Famous, will be in the Market Place with a giant, but simple and beautiful, fire installation based on the pendulum theory of Newtonian mechanics.
Fifteen pendulums, each a large flaming sphere, will sway back and forth at different rates, creating slowly changing magical patterns of fire.
During the day tomorrow local sculptor Laury Dizengremel will construct a Newtonian colour wheel on the corner of Elmer Street and Bluegate.
Visitors are invited to drop by between 10am and 6pm or during the event to add their decorative mathematical equations to the community artwork.
Around the town centre, local community groups will be performing extracts of the Giant Steps audio-promenade drama tour by Craig Baxter, commissioned specially for the festival.
And in Guildhall Street 'Alchemy Jack', Jack Greene, and his assistant will strive to create the 'philosopher's' stone in his secret alchemy lab.
Around 30 local schools and community groups will be taking part in five science-themed carnival processions. Each parade will follow a 20-minute circular route, starting at 7pm and 8pm - leaving from Edith Smith Way, The Conservative Club in Castlegate, the National School in Castlegate, Market Place and Elmer Street North.
They have worked with international parades company Shademakers and local artists to make the processional costumes and images.
A host of other festival favourites - which have been running this week - will also be welcoming visitors tomorrow evening including The Ethometric Museum sound show and apothecaries Floggit and Skarper, from Dizzy O'Dare, both at The George Centre.
St Wulfram's Church will be hosting The National Space Centre's Stardome mobile planetarium and the spire will be used to refract shafts of white light shone by design company Deadgood to produce a vivid spectrum of rainbow colour.
Grantham Museum is staying open until 9.30pm so visitors can enjoy a special exhibition of Ladybird books and more than 40 framed and unframed paintings from two classics - 'The Night Sky' and 'Exploring Space'. They also have the chance to see a rare book by Newton which is normally kept in the vaults.
A number of shops are staying open for the special event and there will be fairground rides in Wide Westgate and food stalls in Westgate and near St Wulfram's Church.
A hog roast and live music will be staged at The Angel & Royal Hotel in the High Street.
Several town centre roads will be closed to traffic from 6pm until 11pm - St Peters Hill, High Street, Guildhall Street, Vine Street, Finkin Street, Swinegate, Elmer Street, part of Avenue Road, Westgate, Market Place, Conduit Street, Bluegate and Church Street.
A number of edge-of-town car parks will allow people to leave their vehicles and walk into a Grantham centre they will find hard to recognize.
Town centre and car park maps will be produced to help visitors.
