An egg needs a temperature of 158⁰F (70⁰C) to set. In 8.2. _________________________ for

the egg white to become firm, proteins in the egg must modify. That won’t happen until the

temperature rises enough to start and maintain the process.

The sidewalk presents several challenges to this. Sidewalk temperature can differ

in direct sunlight or not. Robert Wolke, in his book What Einstein Told His Cook: Kitchen

Science Explained, points out that a concrete sidewalk might only reach a temperature of

145⁰F (63⁰C), which is not enough to fry an egg evenly.

Still, the idea of frying an egg on a sidewalk is so intriguing that the city of Oatman, in Arizona,

hosts an annual Solar Egg Frying Contest on the 4th of July. Contestants get 15 minutes

to make an attempt using solar power, i.e. sunlight, alone. However, some aids,
