Vacuum snap
I don’t know if there’s a more satisfying morning sound in the world than the “ssszzznnnnaaaaaappp” sound of a freshly opened bottle of wheat germ. I don’t know another thing that is vacuum bottled anymore, and it’s probably only a matter of time before they change to some horrible new eco-vacu-bag that will somehow save the rain forest. But in the meantime I will continue to enjoy turning that cap just enough to break the seal, just enough to start to let air into the vacuum as slowly as I can, and then that sudden pop of the lid.
