If it works, you'll erode your surfaces. Then, you'll have sand all over the place. If you attached the sand to a surface, you wouldn't need to vacuum your whole kitchen after every meal. I believe fixed abrasive kitchen products are available.

Will it remove the coffee stains from my teeth?

You can cut a small hole in the exit hose of one of those air-in-a-can keyboard cleaners and then punch it through the neck of a small plastic bottle and seal at either end. Fill the bottle with sand and hold it upright while depressing the trigger.

Voila, mini sand blaster.

What [a1] said (er, linked).
Although having it battery powered (or built onto a hand- held compressed air can) instead of needing a compressor is a good modification.
