Wtf is going on with that stone???

I found this stone near the river "Main" in Germany. I have absolutely no idea why the fk the stone is changing its spinning direction.. anybody an idea?
To proof that I didn´t use any magnets, I put it on the glas table!
It also looks like a prehistoric tool i think.
