In previous years, the youngest showed the most research zeal. This year they follow in the footsteps of Euclid and Descartes through a geometric challenge. Preschoolers and students of lower grades of primary schools will show their creativity and make geometric shapes, figures or New Year's decorations from straws. It's up to them to let their imaginations run wild and send us photos of their work.

We will publish all received photos on November 27 on the Night of Researchers website and the Facebook page of the NOU team.
