Tumblin You Treasure

Put the rocks you find in a rock tumbler to make them sparkle. Tumblers are pretty easy to use, but you need an adult to help you. Here’s a quick get-started list.

Choose rocks about the same size and hardness.

Rinse o the rocks.

Place the rocks in the tumbling container.

Add grit and water according to the instructions.

Be patient! Your rocks need to tumble for about a month. When they are done, store your shiny rocks in a container that shows them oƒ. Clear plastic organizers with lots of little compartments or adjustable dividers work great.

Close the lid.

Set the tumbler in a safe place and turn it on.

Check the tumbler according to the instructions.

Add more grit and water as needed.
