Mars is among hundreds of entrants for the Make it in Great Britain exhibition, which show off the best of British manufacturing at the Science Museum this summer.

The confectioner will present the manufacturing journey of a Mars bar, ‘from bean to bar’.

“We have selected a really exciting mix of exhibits and I hope that as many people as possible visit the exhibition and see all of the great examples of British design and manufacturing – it will be spectacular,” said business minister Mark Prisk.

“Manufacturing accounts for 8% of total UK employment and well over half of export goods, yet current perceptions of the industry are out of date and do not reflect that reality.”
