Positive thinking has an effect. The power of positive thoughts activates a machine.

As part of the marketing campaign for "Life is Good" - a brand from Apparel, the device measures brain waves and reacts to those identified as positive. Activated by these cheerful thoughts, the user can turn on a tap and fill a glass of water. Sounds simple, right?

So why would a brand like Apparel want to do this? The brand wants to show that with confidence and positive thinking, a great deal can be achieved. Apparel donates ten percent of its profits to helping children, and the brand, known for its cheerful T-shirts, also collects images of its cheerful customers on its own website.
