Gold in cow pee – level 2
In India, scientists say that they found traces of gold in cow urine. They made the discovery after 7 years of research on 500 samples of cow urine.
Every sample had gold in it. They took the samples from young cows, pregnant cows and cows who stopped producing milk. The amount of gold is between 10 to 30 milligrams of gold for a litre of urine.
The team says that cow urine can be used for medicine, too.
Difficult words: trace (a very small quantity of something), urine (pee, wee), sample (a small amount of something for testing).
