THE UNSEEN t-shirt changes colour when exposed to pollution

London – As 70% of the world's industrial waste is dumped into bodies of water where it pollutes the usable water supply, according to ConserveEnergyFuture.com, THE UNSEEN is visualising such pollution using colour-changing chemicals.

Created in collaboration with sustainable apparel brand The Lost Explorer, the cotton and hemp t-shirts are made using a natural vegetable dye that changes the colour of the garment when it gets wet. The wearable pH sensor begins as purple to symbolise neutral water, and is transformed into a rainbow of different pigments when wet to demonstrate the red acidity or green alkaline of the water.

The partners also created a video to show people how to make their own version of the t-shirts at home using red cabbage as the key ingredient. The campaign hopes to raise awareness of water pollution by visualising the problem and making it more tangible and relatable to more people.
