Helium is an element and noble gas with the symbol He and atomic number 2; It was first identified in in 1868 during a solar eclipse. In 1903, large reserves of helium were found in the United States, which is by far the largest supplier of the gas today. Liquid helium is used in cryogenics and for cooling superconducting magnets, A major commercial application is MRI scanners but it is also used as a protective atmosphere in arc welding and silicon wafer production. A minor use is as in balloons and airships.
The outer clip lock container contains two film pots, in one is a stamp which is NOT a swap item and in the other the log; a gentle shake will reveal which is which. There is room (just) for small TBs and swaps.
| PLEASE DON’T FORGET TO BRING YOUR OWN PEN OR PENCIL, AND ENSURE THAT YOU POSITION THE CONTAINER CORRECTLY IN ITS HIDING PLACE FOR THE NEXT CACHER TO FIND. |
