Helium Helium Helium (from ) is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements. After hydrogen, helium is the second lightest and second most abundant element in the observable universe, being present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this figure in the Sun and in Jupiter. This
Stone boiling Stone boiling Stone boiling is a moist-heat cooking method. It involves placing heated rocks into a water-filled container to heat the liquid to the point where it can be used to cook. This method of food preparation is a fuel-intensive process and it often requires the heating and reheating of stones before the water reaches an effective cooking temperature. Indigenous peoples in what is now Canada and the United States of America, especially on the West and Northwest Coast, used stone boiling. Cooking this way allowed for a more controlled temperature which made the extraction of fats and oils easier
