WaterDrop is a folding watering tote bag that saves more than 250 gallons of shower water each year. WaterDrop collects the water we waste every day while we wait for hot water to come out of the shower. You can reuse it afterwards for plants thanks to its folding watering can design. The bag collects up to a gallon of water each time to you shower, which you can then use around the house. The idea was successfully funded on Kickstarter and you can get your hands on one for a special early-adopter price right now.
Seems like an awful lot of work every day for only 2 or 3 gallons of water.
