Sidewalk Egg Frying Day
Sidewalk Egg Frying Day is observed on 4 July to raise awareness about solar energy advantages. The event’s name comes from the phrase describing extreme heat sufficient to fry an egg on the pavement. Oatman, Arizona, hosts an annual contest where participants use solar methods, including mirrors and magnifying glasses, to fry eggs in under 15 minutes. Historical references to frying eggs on hot surfaces date back to 1899, with continued interest in various locations including Australia and Death Valley. Scientific observations note that concrete and bricks are inefficient heat conductors for cooking eggs, leading to the use of metal surfaces and pans.
