NASA: where you can check out the uses of liquid nitrogen, purchase your very own star map and establish a healthy distrust of robots from a young age. Dad and Redditor Derwolfe took his 4-year-old daughter to the Johnston Space Center in Houston, Texas, for a day of educational fun recently, and it was mostly going ok-- until dessert. Frozen Yogurt robot at NASA made the cup to her exact specifications, showed it to her, and then took it back. "It was the funniest/worst thing I have ever seen," Derwolfe commented. He elaborated in the post that she had been asking about the frozen yogurt robot "10-12" times since after lunch.
