These are sand from near the Great Lakes, and you can see that it's filled with minerals like pink garnet and green epidote, all kinds of amazing stuff, and if you look at different sands from different places, every single beach, every single place you look at sand, it's different.
Так что в любом уголке планеты, на каждом пляже, где бы вы ни обнаружили песок, он всегда будет разным.
