The idea is based on “Eating an apple a day keeps the doctor away”. It is part of an advertising campaign developed by the German communication agency Serviceplan for OAK, a life insurance company.
The calendar is composed 12 plexiglas cylinders. At the start of the month, you fill the right cylinder with apples. Then, you remove an apple everyday to reveal today’s date. I imagine this concept in a family kitchen. The fun factor could encourage kids to eat more fruits every day. Any ideas for a DIY option?
