Mars bars were first made by hand in Slough, Berkshire, in 1932, and are still made in the town.
“A few people who used to work at Mars’ factories commented [on Facebook] and they said it goes through a machine called an enrober, which is like the waterfall the bars go through,” Mr Seager said.
“Apparently they get blown with air along the top as it comes out of that waterfall. Apparently there’s meant to be somebody at the end who removes the ones which haven’t been hit by the air.
“I don’t know what happens to them then. I suppose they got put into products that have Mars bars in, like cakes and things.”
With regards to other confectionery, Harry enjoys most chocolate bars but is not a fan of all sweet treats.
“I don’t like the strawberry and orange cremes in a box of Roses or a box of Quality Street but I do like the coffee ones. I remember they took the coffee ones out a very long time ago but as a kid I remember them,” he added.
Those Quality Street Coffee Cremes are only available at John Lewis and Waitrose this Christmas.
