Pre-Christmas Physics Show

Digitaler Adventskalender
Zauberei? In einem der Adventskalendervideos zeigt Professor Justus Notholt, wie er Wasser in einem Glaskolben mit kaltem Wasser zum Kochen bringt. Durch die Abkühlung des geschlossenen heißen Glaskolbens sinkt der Druck im Glaskolben, und Wasser verdampft bei geringerem Druck bei niedrigeren Temperaturen.

Physics an Chemistry Advent calendar - online again this year

An exciting program awaits you.

Once again this year, the teams led by environmental physicist Justus Notholt and the chemist Stephan Leupold are creating a digital natural science advent calendar. Every day from December 1 to 24, you can watch an experiment on the University of Bremen’s YouTube channel.

“As our popular physics and chemistry shows cannot take place this year due to the pandemic, we wanted to at least offer our audience a few exciting experiments online,” says Justus Notholt. Last year’s success was immense: The experiments from the 2020 advent calendar have been watched over 1.7 million times.

This year, the scientists and their teams will present 24 new experiments from the fields of physics and chemistry. “For example, we’ll be showing a stumbling sponge, an imploding beer barrel, secret scriptures, burning aluminum, and optical illusions. We hope the audience - big and small - enjoys it!,” exclaims chemist Stephan Leupold.


Traditionally the public "Physics Show in Advent" takes place every year in the pre-Christmas period. Many exciting experiments from various fields of physics are demonstrated. All those who are enthusiastic about physics and technology are invited, especially pupils and young people with their parents and teachers.

Staff from the Physics department and Physics laboratory demonstrate the fascination of physicsand the relation of physical phenomena to everyday life :

  • What influence does the Coriolis effect have on on certain weather phenomena?

  • How does temperature change the characteristics of materials?

  • What happens to a beer bottle in an ultrasonic bath?

  • Why is the sky blue and the evening sun red?

  • Is it possible to transmit music with a laser beam?

We answer these and many other questions with some Christmas experiments.
