The Light-year Water Bottle

The bottle holds the amount of water it would take to stretch one light year, if all the molecules were laid end-to-end in a single file line. The amount of water it takes for that monomolecular line to reach 0.1–0.9 of a light year are also marked, as are a few other curious and unusual volumes. Available for purchase with any subscription plan, or as a standalone item in the Member Store for existing subscribers while stocks last. Add the Light-year Water Bottle to your cart, then choose your subscription plan and use the promo LIGHT at the checkout to get the bottle for free!
