The Need/Want Glass from Alesina Design encourages you to think about wasting water every time you take a drink. By holding your finger over a hole in the glass, you consciously permit yourself to have more water than you might “need”. This is all subjective I’m sure, and if you could somehow apply the concept to watering your lawn or taking a bath it might be even more effective. Still, got me thinking. Each glass is hand finished, numbered, and signed. Available here.
