British gunners in WWII were able to locate and shoot down German planes at night due to the invention of radar, which the Germans knew nothing about. To cover up the invention and extreme effectiveness of radar, the British spread about an urban legend that said that they massively increased the night vision oftheir pilots by having them consume large amounts of carrots. This lienot only convinced the Germans, but also had a bonus effect of causing manyBritish people to start planting their own vegetable gardens, including planting carrots. This urban legend has persisted even to this day.
The demand for lemons and their scurvy-preventing properties, a disease that causes bleeding gums, hit a peak during the California Gold Rush of 1849. Miners were willing to pay huge sums for a single lemon. As a result, lemon trees were planted in abundance throughout California.
It is actually possible to turn your skin a shade of orange by massively over consuming orange carrots. Orange carrots get their bright orange color from beta-carotene.
Lemon trees bloom and produce fruit year-round. Each tree can produce between 500 and 600 pounds of lemons in a given year. In addition, California and Arizona produce 95% of the entire U.S. lemon crop.
The largest carrot ever grown was 19 pounds; grown by John Evans in 1998 in Palmer, Alaska.
