An earbud coupling has a rear portion forming an earbud mount that easily attaches to a hemispherical earbud, and has a front portion forming an in-ear mount that can be pressed into a person’s ear canal to hold the coupling to the person while blocking environmental noise. The system elevates the food to a more ideal position for consuming the food andor water. Sliding longitudinal displacement of the retainment arm allows for progressive engaged rotation of the blade shank about a pivot mounting point to a fully closed and locked position against two blade shank engagement points by the locking arm. The region is then doped with suitable dopants, e. The warmed stream then flows to the bulk storage tank. The substrate containing glass forming raw materials may be formed so as to have a Young’s modulus of 110 or higher.
