For his birthday, Jonas received a rock polisher from Grandma and Papa. He has been really into all things science, so he was excited to try it out and see what happened to the plain looking rocks that we had.
You begin with a set of unpolished rocks:
And after several cycles in the tumbler with different grits and polishes, the rocks turn out looking like this!
Jonas was pretty excited about how smooth and shiny they all were, and he plans to use some of them to make some jewelry as gifts for Christmas. Thanks for the fun present, Grandma and Papa!
