Bought it for my grandson. He calls me every time a batch is done to show me the stones.

Every child has a pocket full of rocks this makes them shine

The Rock Tumbler Kit turns ordinary rough stones into smooth, polished gems. Put the stones in the barrel, set the timer on the digital panel for up to nine days and pick one of three speeds. The barrel turns slowly under a cover that keeps the noise down, so it can run in a bedroom or on a kitchen counter.

When the timer is done, take the barrel out, rinse it under the tap and see what came out.

How it works with the Rock Tumbler Kit

Four steps. Nothing complicated.

Step 1.

The tumbler arrives with its leak-proof barrel and stainless steel lids.

Step 2.

Fill the barrel with rough stones, water and polishing grit, and close both lids.

Step 3.

Set the timer and the speed on the panel and press start. The cover keeps it quiet.

Result.

Days later, rinse the barrel and pour out smooth, shiny stones.

What actually makes a good rock tumbler

What actually makes a good rock tumbler

Three things make a rock tumbler that kids actually finish a batch with.

A timer. Nobody remembers to switch it off after a week. This one does it itself.

A barrel that does not leak. Steel outer and inner lids keep the water in.

Quiet enough to live indoors. The cover means it can run in the house, where kids can check on it.

One batch always leads to the next

One batch always leads to the next

The first batch is the moment: the barrel opens and the stones that went in dull come out shining. After that every walk becomes a hunt for the next batch.

It is a gift grandparents like to give, because it is a project they can do together.
