It's not normal vomit, mind you, it's whale vomit that this 8-year-old British boy found on a trip to the beach. The substance is called Ambergris and it's valuable because it's used to create perfumes and food flavoring.
Ambergris has a fecal smell when it's fresh, but as it dries, it starts to have a more pleasant smell. During the middle ages, it was used as means to ward off the plague, because it had a nice smell, and people thought that bad air was the cause of the terrible disease.
The substance is really valuable. The boy we mentioned earlier, found about a pound of the stuff while he was out on the beach. The family is estimating that it could bring in up to $60,000. However, experts think that a more realistic number is about $6,000. Not bad for a bunch of whale sick.
