While snorkeling in Bali, a teenager from Massachusetts decided to mock the behavior of fish and lure shrimp into his mouth to clean his teeth.
And it worked.
Russell Laman, 13, has been diving with his dad for seven years. They found a fish "cleaning station" where the shrimp waited for "customers," near an outcrop of sponge growing on rock, and Russell opened his mouth wide, holding his breath for longer than 40 seconds.
With his mouth open, his father caught the shrimp on camera doing their job, cleaning between teeth, looking for particles of food.
Russell said the shrimp darted out of his mouth as he closed it slowly, getting ready to reconnect with his air supply.
So how was it, compared to the standard dental cleaning?
"It felt like tiny little dentists picking away at my teeth and scuttling around my mouth. It tickled a little but not too badly."
Maybe don't try this at home!
