A few weeks ago before we moved our youngest needed to find his favorite rock. We sent two hours on our hands and knees looking for it. Well the favorite rock got an upgrade. Star, grandma and him put it in a rock tumbler than painted it. We'll never lose this one I don't think.
@Cigarguy101 I used to tumble rocks. You have to tumble each rock 24 to 48 hours in each of 3 different grits, from rough to fine...and then the rock is finally smooth and perfect.
