Great little tumbler for kids to learn about mechanical "weathering" (polishing) of rocks. Just like in a stream the rocks are rolled over and over in a grinding powder. In a stream or river the grit would be sand and fine dirts and clays. In this kit the grit and polish are provided. And it only takes about 6 weeks to polish the rocks unlike months and years in a stream!Refill kits available.
