How to build your own hot tub

Hot water beach on New Zealand's Coromandel Peninsula is a big tourist attraction, and for good reason. Thanks to volcanic activity a few billion years ago, there are molten hot rocks under the sand that heat up the water and, if you dig a hole, the hot water bubbles up into your very own hot tub on the beach. Here's how to do it in a few easy steps:

1) Rent a tiny shovel for $5.

2) Walk around the beach feeling for hot sand.

3) When you find hot sand, start digging. Note: The water coming up can reach 140 degrees F, so it's important to dig a pool that mixes hot and cold water. Getting this right is an art.

4) Relax and enjoy the fruits of your labor. (Notice that Brook has created a hot water stream to mix with the warm water in the pool.)

5) Take a refreshing dip in the ocean and call it a day!
