Why Yooperlite Rocks Glow

Erik Rintamaki of Michigan is an avid rock collector. While searching for agates along Lake Michigan in 2017, he found stones that glowed under ultraviolet light. This is how he discovered a previously unknown mineral: yooperlight.

The name comes from the word "yooper" -- someone who lives on the Upper Peninsula of Michigan. Rintamaki has trademarked that name. The scientific term is "cyenite clasts containing fluorescent sodalite." These stones were brought to Michigan from Ontario by glaciers thousands of years ago. You can learn more about yooperlites in this video by Wonder World.

We had a small wild kitten fall into a pipe under my mother's house. My daughter and I tried in vain for an hour to get it out. Finally, I had a thought. I remembered how kittens have such tiny little claws that are like fish hooks. I figured it was probably very hungry by now. It could have been there for a day or 2. So, I took a pair of pantyhose and smeared gushy soft cat food on it. We lowered it into the pipe and the kitten was sooo hungry! She latched onto the pantyhose and tried to eat the food and while she had her claws stuck in the nylon we pulled her free. "Annabelle" is doing quite well, 2 years on. She is a happy cat and lives with my daughter.
