I’ve heard that a good place to find meteorites is in the gutters of your roof. Put a magnet into a plastic bag. Flush your gutters into a bucket. Swish the magnet around the contents of the bucket. Rinse the magnetic meteorites off of the plastic into a separate container.
The idea is that we are dusted with very, very small meteorites all the time. Much of it lands on roofs, and is flushed into the gutters. Obviously this ‘space dust’ is not something you’re going to see on Meteorite Hunters, and there are also ferrous materials of terrestrial origin that gets blown about. ISTM that collecting meteorites from roof gutters is an exercise for people who want to test the theory and want to go to all of the trouble of doing it and then identifying which bits come from space and which ones don’t.
I’ve heard that there’s only one person who has been known to have been hit by ‘A Meteorite’. (IIRC it came through her roof, bounced off the floor, and hit her in the thigh.) But since a ‘meteorite’ (as opposed to ‘A Meteorite’, if you follow) is matter that has come from space and has reached the surface, I think even microscopic ‘space dust’ counts.
Thus: Do we have meteorites falling on our heads all the time, and we don’t know it?
