Magnetic Sand
They say you learn something new every single day. And the things we can learn about the world around us are truly magnificent. Like sand for instance. People who visit tropical islands like Bermuda probably never realized sand could be so pink. Who knew sand can also have magnetic effects?
When this person visited Tahoe, he accidentally left his iPhone on the sand which left an incredibly cool shape that almost resembled a crop circle on his phone made out of what looked like shiny black glitter. This was caused by the magnetite and ferromagnetic elements rich within the sand.
