Haha the sand, IS REALLY BLACK IN COLOR.
Initially I thought it is fake you know, thought is just simply stone, big stone by the beach, and black of course, but after i step on it, and touch it, yes is really black sand.
Kinda not use to it, since i never in my life see a black sand before.
And guess what, unlike other sand, the texture of it is SUPER SOFT!
Derick said it is because there is a lot of a kind of mineral in the sand which can be found on the moon. o.o
Anyway trust the future geologist yo.
