Kelly Caviness built the park for his family. There's a waterslide that twists and turns and leads straight into the pool.

He told Inside Edition: "You will really never get bored of this pool." 

Caviness builds the pools with safety in mind, making sure everything is placed in the right spot so no one gets hurt jumping in. 

But some of the self-made backyard theme parks not built by professionals seem rickety, and may pose a safety risk.
