Color Change T-Shirt Can Detect Water Pollution In Different Cities. Do You Want This T-Shirt?

Find a white T and buy a purple cabbage. You can make one of these. T-shirt 。 The Unseen, a creative material studio in London, CO operated with the British lifestyle company The Lost Explorer and launched a discolourable T-shirt on June 5th World Environment Day.

After being washed in water with different pH values, the dark purple T-shirt will start to change color. Davidde Rothschild, the founder of The Lost Explorer, used to wear such a T T-shirt and deliberately squeezed the juice of a whole lemon to her clothes in front of people. The people around him started to think he was crazy, but soon their critical expression changed. "Just like watching bees pollinate, the process of color change is very wonderful and harmonious, and they can't understand why." David said.

The color of T-shirts will change when they encounter different water levels.

According to the world clothing and shoe net, Lauren Bowker, founder of The Unseen, washed three T-shirts in London with tap water, acid rain and water in Dead Sea, which turned into light purple, pink and light yellow. Of course, this T-shirt can also produce more colors, for example, the water with 3.5 pH value can turn it into deep purple red, and in the water with pH value of 8 and 9, it can turn into faded Tibetan blue and forest green, respectively.

The secret behind it lies in the dye of clothing, the juice of purple cabbage. Purple cabbage contains a lot of anthocyanins. This natural pigment is a kind of PH indicator. It shows different colors in the presence of different acid and alkaline liquids. Roughly speaking, the pigment will change from red to purple and green in the range from acid to neutral to alkaline, and yellow will appear when pH is greater than 12.5.

Therefore, The Unseen and The Lost Explorer think that when people can travel to different cities with such T-shirts, washing with local water can detect the pollution of the effluent.

But this T-shirt is not for sale. The two founders of The Unseen and The Lost Explorer hope that people can make such a dress on their own. They have also launched a video, which is shown to us by Lauren Bowker. dyestuff And will clothes Dyed purple. The purpose of this is to connect people with nature, based on the theme of this year's world environment day, "Connecting to Nature".

In Lauren Bowker, it's a powerful way to connect people with the environment through fashion: "Trump declared that the United States had withdrawn from the Paris agreement, which was very shocking. But do people really understand what this means? Maybe not, because not everyone knows about politics. But if I see that when a car passes (splashing water) or is too strong that frogs can't survive in it, let a T-shirt change color, I will understand.
