There are many tutorials in the internet, but most of them can´t guarantee the realness, of the finds.
The question is: How can we get sure to find real meteorites without an expert?
How it works:
1. put a bowl with water to your balcony, or garden.
2. make sure, no birds can swimm in this bowl. (it would contaminate this experiment)
3. wait one or two weeks
4. put a magnet into this bowl and fish all small metalpieces out of the water.
This finds are spacetrash, or meteorites.
If you watch this pieces under a microscope you can look for rates of stone.
This pieces will be 100% meteorites.
but the most of them will be 0,2mm - 0,5mm
Attention: Sometimes it took very long to get one, but be patient. It works :)
