Ever wondered how rocks, lollipops, and other candy sweets are made? We visited London store Spun Candy for a masterclass on the process. It all starts with sugar syrup boiled to 155 degrees C.

We went along to Spun Candy in London to find out how they're made. And as a bonus, use the code "BI2015" on Spun Candy's website or in stores until September 30 for a discount on products.
