Recently, a team of scientists wondered how and whether fetuses near their due date, between 32 and 36 weeks, experience taste. To figure it out, they exposed fetuses to the flavor of either carrots or kale, via a pill taken by the mother. Then, they used an ultrasound to observe the real-time facial reactions of the fetuses.

Certain combinations of these facial movements were of particular interest—they combined to form a “cry-face” or a “laughter-face.” If you’ve ever eaten carrots or kale, you can probably guess which caused which.
