In Hot Water

Danielle and her family went to a hot-springs pool after a day that included ice skating on an outdoor rink and a horse-drawn sleigh ride through the snow. They were staying at a resort hotel that had hot springs.

They checked out the spot where the water was bubbling out from the ground, sending up wisps of steam. From there, the water flowed into a pool about the size of a small swimming pool. The sign said the water in that pool as 105°F (41°C). The water flowed down from there to another pool where the temperature was 98°F (37°C).

They stayed in the 98° pool for about ten minutes and then went to the 105° pool. Danielle enjoyed sitting right where the water was flowing from the spring.

A man with a nametag that said “Charlie” came over to where the water was coming out of the ground and dipped a little glass container in the water.

“What are you doing?” Danielle asked him.

“I’m just testing the chlorine level,” he said.
Danielle had seen the lifeguards at the pool she belonged to back home test for chlorine.

But when the man walked away, she said to her father, “I think you ought to tell the people who are in charge here about that man. I bet he doesn’t even work here. Maybe he’s looking for a chance to steal somebody’s wallet.”

“What makes you think that?” her father asked.

Can you figure out the answer?
