Hello friends,

Collecting rocks and minerals is a fun way for kids to learn about geology!
Most kids are naturally inclined to pick up any ‘pretty’ rock that they see, which provides a great learning opportunity.
If you’ve ever been to the beach, you’ve probably picked up rocks that are perfectly smooth and rounded. Why is this? The ocean is a natural rock tumbler: as rocks are rolled by the waves and rubbed against sand and each other, their rough edges and corners are filed away.
A rock tumbler can mimic this process and even take it a step further by adding polish to make the stones shine. Rock tumblers work much faster than the natural rock cycle of the ocean (more on that here!) because their motion is constant and delivers continual pressure.
Rock tumblers have long been an HST customer favorite and we often sell out of them. We expect this new line to sell quickly, so make sure to get your order in now!

Plus, if you're a member of our My Science Perks program, you'll earn a $5 reward when you purchase one of our new Tumble-Bee rock tumblers!*
