If you’re like us, then cannabis obliterates your short-term memory. We once tried to lock our car with a key for at least 30 times at a concert, and we didn’t even drive there. Luckily for us, and others like us, there’s the Dot—a hydration bottle with an LED light on it to tell you how many times you’ve refilled it. This way you can visually see how often you have refilled and enjoyed your water—a perfect match for strains that cause cotton mouth. No longer will we accidentally bust our bladders by over-indulging in H2O.
