## Introduction: Campsite Rock Sculpture

Balancing rocks at your campsite can be both decorative and therapeutic...and just about anyone can do it!

CAUTION!!!  Snakes like to live in and around rocks! Be VERY careful not to stir up something nasty! (yellow jackets and black widow spiders like rocks, too!)

CAUTION!!! Falling rocks can crush your toes! Be careful!!!

Please remember to 'Leave No Trace'!  Take down your scupture when you depart public areas!

## Step 1: How to Balance Rocks

An object will balance when its center of gravity (the place where all of its mass, on the average, resides) is over the point of support. The larger the base, the more stable the object is.

Find rocks that look like they’d be difficult to balance…or pick easier rocks to stack…the challenge is all yours!

## Step 2: Size Doesn't Matter

Small rocks are fun to balance, too and can be a real challenge!

## Step 3: Strong Base!

A good supporting base is important. Place your rock on a flat surface...or in a niche

## Step 4: Extra Help

Sand beneath the base can sometimes be used to steady it.
