Cabbage as litmus
A fresh head of red cabbage can be used instead of litmus. With baking soda, they turn green easily, and with a little vinegar, they turn red again! Participants-authors: Jelena Mrmošanin, Jovana Krstić...
A rich and diverse scientific and popular program has been prepared in Nis this year as well. Scientists and researchers from various fields will welcome all curious minds on the Summer Stage of the Niš Fortress. We will walk through the Niš Fortress and study the testimonies left behind by the peoples who used it, and you will also hear interesting facts about its history and architecture. While walking around the Fortress, sweeten your life with instant ice cream. Liquid nitrogen will ensure a pleasant atmosphere without heat. Through the time machine, we take you to Naisus, to the site of Mediana, in the distant 4th century and the time of Constantine the Great. Be part of a virtual journey through unknown landscapes and cultures, which Constantine created and kept secret until this day when he will tell us and show us everything! You will also learn what migration brings through language and culture and why intercultural communication is necessary. And finally, who managed to convince the Minister of Construction that it is necessary to build a tunnel in the plain? Did you know that populations of some species cannot survive without migrations, as well as without migration corridors?
Migration as salvation? Come check it out together! We are waiting for you on September 30 from 17:00 to 24:00 in the Fortress of Niš!
