I have just had a very strange experience, and would like to know if there is an explanation for it. There was a small tin of black olives on my kitchen work surface. I put a teaspoon into the tin, to get an olive. The moment I did this, I heard what sounded like a radio broadcast of a football match. I could clearly make out the sound of the crowd. I could hardly believe what I was hearing, as I have never experienced anything like it before. When I removed the spoon from the tin, the sound stopped. I tried it again by putting the spoon back in the tin, but the sound did not happen again. I have tried to find any information online, to discover if such a thing is possible, but have found nothing. I was not the only person in my house to hear it, so I know it wasn't my imagination.
