did i ever tell you guys about how my brother left his ipod shuffle in his pocket once and my mom put the pants they were in in the washer so the ipod shuffle was ruined and my parents got him a new one but we kept the old one and then after a couple weeks i was like “you know what sometimes stuff just needs some time to air out. i’m gonna see if it still works” and i put it on the charger and charged it and the only song on it was In The End by Linkin Park
This is Alexandrite, it’s also called “emerald by day, ruby by night”
It changes colour based on whether the light source is from the sun or from a candle.
It does this because Alexandrite strongly absorbs yellow light due to chromium ions in its crystal structure, leaving the other colours behind. Light from the Sun emits all colours, but it peaks in the green, and our eyes are most sensitive to green, so in Sunlight Alexandrite is green.
Incandescent lights are things like candles and filament light bulbs. They also emit all colours of light, but they peak far, far into the red, so there’s not nearly as much green or blue, so under those, Alexandrite is red.
Gemstones are awesome.
Yo forget diamonds, gimmie THIS as a wedding ring.
This is awesome, this is my birth stone and I never knew it did this! most of the time it just looks kinda grey-purple. Now I want more stuff with my birthstone in it!
The wheels take impact and stress off your legs, and the position helps your spine, but you’re still doing running motions instead of biking motions, so your legs are getting a good workout, and you can go for longer
