A Vial of Acid in the Freezer would be somewhat analogous to having healthy Respect of the Power of Fire;
One would (hopefully) know not to get too close, or to **** with it too much, once One has been burned by it before.
Though, I do declare, it can be a great source of warmth and inspiration in proper moderation, company and contexts.
A Vial of Acid to be used very sparingly, such as for seasonal Acid Parties would be the ****. Each Solstice or Equinox, for instance.. that'd be ******* cool.
