Here is a well-designed way to make use of water, a scarce resource that has become hard to collect in some countries. The invention is called the Raindrop Mini, an eco-friendly brainchild by Studio Bas Van dere Veer.
The device fits in-line with the drainpipe and channels rainwater into a removable jug; rather than demanding you accomodate a water-butt, water is collected into the watering can itself. The solution is a great idea to water plants and store water the eco-friendly way.
The Raindrop Mini is actually available in Europe right now but prices remain to be unknown.
