User: Why are pools fun?
Assistant: Pools are fun because they help to keep people cool when it is hot outside.  Kids love jumping in pool and playing with other kids in the pool too.  Sometimes water slides are connected to pools to offer more fun.  Pools are a great way to relax in the sun, get a tan, or socialize with your friends.  They do have a fair amount of upkeep during the very hot and very cold seasons of the year.  Pools can freeze in the winter and also develop algae in the hot humid weather too.  Chlorine is used to disinfect pools and neutralize in viruses and bacteria.
