Spanish physicist Manuel Linares has developed a brand of ice cream that changes color when it experiences a change in temperature and comes into contact with saliva — but he's keeping quiet over how he came up with this delicious creation.

He calls it Xamaleón, a play on the Spanish word for chameleon. The tutti-frutti flavored ice cream starts off as a periwinkle blue, but then changes into purple and pink as it's being eaten. Linares calls his secret ingredient the "love elixir," and he's being tight-lipped about how it works. Whatever it is, the mixture appears to react to changes in temperature and the acidic quality of saliva.

"As a physicist I know that there are various possibilities that might work and I was delighted when I managed to crack it and create an ice cream that changes colour," he was quoted as saying in The Mirror. "It was important to me to make sure I only used natural ingredients, so it took a bit longer. And as to the trick, I am not giving out too much detail because the patents are still going through."


Xamaleón also includes strawberries, cocoa, almonds, banana, pistachio, vanilla and caramel. It's apparently so popular that business at his ice cream parlour in the town of Calella de Mar, in the east Spanish province of Barcelona, is booming. Looking ahead, Linares wants to create an ice cream that turns from white to pink, and another one that glows under ultraviolet light.
