You may be thirsting for a tall glass of cola, but do you really need all those calories? The Want Need Glass features a hole and a line dividing your need from want. If you require more water than you need (above the line) then you’ll have to cover the hole with your finger – as in, take the matter into your own hand to make a stop to waste, which leads to thinking of making a stop to waste in the global sense. While the glass is intended to make people more aware of the waste they’re causing when having or using more water than needed, I like the cut back on soda idea better. After all, we could all benefit from drinking a bit more water each day.
