Researchers at Stanford University made the skin of mice transparent using the yellow no. 5 food dye, otherwise known as tartrazine, that's typically found on Doritos.

A commonly used food coloring can make the skin of a living mouse transparent, allowing scientists to see its organs function, according to a new study.

It’s a strange occurrence, seeing a mouse’s skin turn transparent as you rub food dye on it. The researchers say it gives you a complete look into the mouse’s body, showing the blood vessels, organs, and everything else inside.

Researchers have developed an ingenious way of making mice transparent, so that you can see their little organs, veins, and all their other fleshy circuitry with the naked eye. The secret? Doritos dust.
