The company Juicy Drench, which specializes in the manufacture of vending machines for selling drinks, has developed an unusual machine that "does not take money" from customers.
Instead of money buyers are supposed to accomplish various logical tasks which require certain alertness and vigour of understanding.
There up to 40 different tests and tasks in the "menu"... from complex mathematical problems to simple tests for understanding and logic. To get familiar with these tasks and tests one can visit the company's website http://www.staydrenched.co.uk, where they all are in the public domain.
After passing the test on memory and logic, customers receive a bottle of drink for free.
The main idea here is to show customers that dehydration leads to a deterioration of memory, intellect, and vice versa, drinking plenty of liquids contributes to the proper working of the brain.
