Investigator Henry Kleta sent us this note:
I’d love to report a long-running experiment that has been started by coincidence and is running now nearly 25 years.
Round about 25 years ago my dad tried to seal the roof of our house with tar. A whole bag of that stuff was left over and was thrown on top of the old oven (used to melt that stuff) and was long forgotten somewhere in the depth of dad’s garage. The whole equipment was – luckily for the scientific community –
forgotten and kept in peace all the time.While reading the article in AIR volume 7, number 3, “The latest on long-running experiments,” the pictures of that old equipment came up and I started to dig through dad’s garage to check the “experiment” he has started without knowing it.
I’ve enclosed a picture of the bag of tar after turning it around to check the results of the experiment. See the picture here.]
I hope to be able to continue the experiment and will happily report every ten years the results.
