Broken Hill Crystals

Today we went to the Broken hill crystal mines and we went to the museum, in the museum there were crystals like this one⬆️.

Down here is a video of my brothers and me, from the crystal shop we got these Hematite beads that are really strong magnets. When you throw them in the air in each hand they come together when they're in the air and when they come back down you are supposed to catch them, but if you drop them they lose a bit of magnetic but if you keep dropping them [like my little brother!] then they get really bad.
