We created a calendar that works thanks to chemical reactions. Each ampoule represents one month of the year. The change of the days is shown thanks to the chemical reaction of the special organic liquid with the oxygen. Evaporating, the liquid level indicates the date of the month and day of the week.

Each ampoule has different chemical elements to make sure that the liquid will react on the precise day of the year. We have tested our formula during two years to prove that it will work fine in different environments.

The Chemical Calendar has a great response to clients. The new BASF annual calendar reminds about the importance of chemical innovations and demonstrates the main values of the brand.
