Nature has suggested scientists a new way to protect ATMs.
Employees of the Swiss Higher Technical School of Zurich have developed a special film, which, when damaged, produces a very hot foam to protect against malicious acts. Scientists suggest using this technology to protect against vandalism and theft from ATMs.
The developed film is a huge set of microscopic plastic honeycombs arranged one above the other and filled with hydrogen peroxide and manganese dioxide. When the honeycomb structure is damaged, the two substances mix and create a foam, whose temperature is 80 ° C.
For this development, scientists inspired the defense mechanism of the bombardier Beetle . The essence of the mechanism is that, feeling threatened, the insect produces a powerful chemical spray that forces any predator to retreat. The spray consists of hydroquinone and hydrogen peroxide (they are stored in two separate insect glands), which are mixed in a special tank, and then heated to 100 ° C and flies towards the aggressor.

The author of the development, Professor Wendelin Jan Stark, believes that his foam is perfect for protecting ATMs from thieves and vandals, as the current protection options for cash machines are very complicated and expensive to manufacture, and the cost of this film will vary from $ 40
As part of the test, scientists added blue paint and DNA nanoparticles to plastic honeycombs. As soon as the film was damaged, it released paint, making the banknotes useless. Moreover, each banknote was tagged with DNA particles, which in the future makes them more traceable.
