Scientists Facts

Miners in Mexico found a hidden cave in 2000 with the largest crystals on Earth. The crystals were white gypsum beams up to 37 feet long and 3 feet wide. The heat inside hit 136 degrees with near-total humidity. Without a cooling suit, a person can die within about 10 minutes. In 2015, the mine flooded and sealed the cave shut.

Lonnie Johnson, a NASA engineer, invented the Super Soaker by accident - a burst of water shot across his bathroom during a heat pump experiment. The toy went on to sell nearly $1 billion. When Johnson discovered Hasbro had underpaid his royalties for years, he took them to arbitration and won $72.9 million.
