One of the reasons I want a snowfree environment, is my discovery of a cool experiment in November last year. A couple of days before the winter kicked in, I learned about the micrometeorites. Dust from space fall to earth, tons of it every day. But every individual piece of stardust is too small or almost too small to see for the human eye. But with a magnification of just 20, they are easy to identify.
The meteorites we are talking about here are the iron-containing ones. When they enter the atmosphere, they melt and get a characteristic round shape which is easy to identify in a sample.
NASA and others have published lots about the topic, including photos and how-to's. The way I search for the extraterrestrial dust is the easiest one, I think. I use two plastic cups. Inside one of them I put a strong neodium magnet. The second cup I place on top of the magnet, locking it between the two cups. Then I tie strings to the cups in a triangular shape, allowing me to walk straight and hold the cups just centimeters above the ground. With this you're ready to hunt for the stardust, taking your cups for a stroll or three. The micrometeorites will be attracted to the magnet and stick to the bottom of the cups. To check if your sample contains the round beads, transfer it to a post-it note and look at it with 20x magnification or more. Good luck hunting!
