On my way back from Israel after one of my pieces of luggage went through the x-ray machine the security guard made me take it over to the main security station. I got all nervous because this specific piece of luggage contained 2 weeks worth of dirty laundry. I couldn’t stop praying to Hashem that they shouldn’t open it – as I was rightfully embarrassed. They started questioning me; The reason for my visit? How we traveled? the places I had been to? They then asked me if I might have any batteries or such things, I said I might in the front pocket.
To make a long story short they asked me if I had been to the dead sea and when I answered in the affirmative they asked if I brought back some mud or such. I reminded myself that I had a bag of mud that they provide by the beach. It appears that on the x-ray the mud looked like a kidney and they wanted to make sure I wasn’t transporting one.
I was so thankful they believed me and didn’t make me open the suitcase. I don’t know why they would have thought that I was transporting a kidney since it wasn’t laying in dried ice etc.
