Dippin' Dots
Beaded "ice cream of the future" invented in 1988 by microbiologist Curt Jones, who flash-froze ice cream mix in liquid nitrogen into tiny spheres. Served in a cup and eaten with a spoon, Dippin' Dots became a quintessential 1990s amusement park and mall treat — a novelty that felt futuristic and tasted like the 90s.
