People purchase rock tumblers to polish rocks. These machines range drastically in price and spin the rocks against each other in a machine to make them shine.

Sweeping the ice in front of the stone polishes the pebble (bumps in the ice) and remove any frost and debris that may be in the rocks path, therefore sweeping makes the rocks go faster and also causes them to go straighter (not curl as much)

Glacial polishing is the process by which a glacier smooths and polishes a bedrock surface as it moves over it, causing striations and a shiny, polished appearance. This process is primarily caused by the abrasive action of rocks and sediments carried by the glacier as it moves.
Some safe and non-toxic options for kid-friendly nail polish include water-based nail polishes, peel-off nail polishes, and nail polishes that are free from harmful chemicals such as formaldehyde, toluene, and dibutyl phthalate.
I think almost any country will produce nail polishes. OPI is from somewhere in Europe, and there are many nail polishes that you can purchase in Asia for very low prices.
A rock polisher very much does what it says on the tin: polishes rocks. Often they work by tumbling rocks along with a polishing agent. This is sometimes done purely for decorative reasons to make shiny pebbles. Other rock polishers have industrial applications, for example in the manufacture of granite kitchen work tops.
