Want to save some of that water that washes down the drain as you adjust the temperature of your shower? The Joeycan is one of those simple, elegant ideas that you wish you'd thought of yourself, catching the shower water for you to empty on your plants at a later time.
The Joeycan is essentially just a weirdly shaped piece of plastic. Designed to lay down while you get the shower ready, it has a specially designed top that captures the water, with a curved spout to stop it running out as the can fills. The Joeycan is Australian designed and made, and can apparently save up to 1000L of water per household per year. For $30 plus shipping, it wouldn't take too long for it to pay itself off, and you could shower a bit easier knowing you weren't washing money completely down the drain.
