Keeping flowers or plants in your house is supposed to make things more beautiful, not chaotic. But this vase is only balanced when the flowers have water. If too much liquid evaporates, the counter-weight pulls one side of the vase down.
"Water Balance" was designed by Risako Matsumoto, who is part of the design collaborative Design Soil. Maybe things in your house are messy enough that you wouldn't even notice, but it seems like it would be weird to come in from your day and see something askew on the wall. It would be a solid visual reminder to give your flowers and other plants some water, though. [Spoon & Tamago]
