When it comes to innovation we love it, but not just anything. AOK has come up with a calendar that not only tells you what day it is, but also helps you stay healthy. Basically, this calendar is a tube made of UVA- and UVB- resistant plexiglass and this tube is filled with apples in the beginning of every month, so the number of apples in the beginning will vary according to the number of days in the month. Everyday you take out one apple from the tube (eating it of course) and as you take it out the remaining apples will move up, which will reveal the date. This way this calendar will not only keep you up-to-date, but also your health, by keeping the doctor away every time you eat an apple.
