At the right is a worthy counterpart. This felt-tip pen was removed via fiberoptic gastroscopy from the stomach of a 76-year-old woman. It had been in her stomach for 25 years, but after removal it was still functional. It makes one wonder whether she was achlorhydric, but the report at the British Medical Journal does not comment on the acidity of her stomach (CT scan at the link). Via Neatorama.
And for you young whippersnappers who don't remember the early years of television, here's a sample Timex commercial. Notice that it's two minutes long.
Most cheap pens have been made with HDPE (High Density PolyEthylene) which does not react with the hydrochloric acid (HCl) or salts (KCl & NaCl) found in gastric juices.
ReplyDeleteNot to sound condescending, but I don't see why the pen should have gastric damage or any reason to suspect she was achlorhydric. I would expect the same result if a glass marble or another non-reactive item were swallowed.
