How can I use my Smithsonian rock tumbler?

I have one from Smithsonian that I bought my son for Christmas and I lost the directions.

This is a small barrel tumbler that comes with Tumbling Grit. To make it work, you should fill the barrel with about 1/4 inch of water, about 2/3 full of rocks and then grit. You want a mix of water and grit that doesn't just wash off of the stones when the barrel turns, so you want it to be a slurry consistency like a paste almost. The idea is to have the grit stick to the rocks.

Ideally, you want to polish your rocks in steps, using progressively finer grit each time, and finally a polishing compound. You start with coarse grit, a second finer grit, a third grit, and a polishing step. Each step may take as long as a week of tumbling.

Sand is a very poor tumbling grit, and will take much more tumbling time to produce the same result, plus you cannot use sand for any rock that is not softer than quartz, and many attractive Tumbled Rocks are some variety of quartz.
