Ice cream is an exciting treat to have all on its own, and now a certain type can change colors when you lick it. A Spanish scientist has created a formula for ice cream than changes colors when exposed to new temperatures and different levels of acidity found in saliva. The product is called Xamaleon, and supposedly has a "tutti frutti"-like flavor.
The product starts out as a periwinkle color, then changes to pink and then purple after it's been licked. The creators of the color-changing ice cream say their next project will be a flavor made with medicinal plants that cause an aphrodisiac effect.
