Glass in my finger!!

Yesterday when I was walking to the shop that we live close to. I had found a broken calculator. Being the idiot I am, I thought hey, a calculator! I must break it more! The LED was smashed and one teeny tiny little bit of glass got into my finger. I only got it out later that night when my dad suggested that we needed to use his freaking microscope! Apparently the bit of glass was 400 times smaller than what the human eye can see!
