Sunday's triple digit heat kept lots of people indoors, but some braved the weather to spend the day poolside.
At Inskip Pool in Northeast Knoxville, more than 1,000 people visited the pool over two days to stay cool.
Long lines of people waited at the diving board, hoping to show off the best cannonball.
Managers at Inskip say normally fewer people visit the pool when it's this hot.
