A Stumbling Sponge, Secret Scriptures, and Burning Aluminum

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.

Magic? As part of an advent calendar, Professor Justus Notholt shows how he makes water boil in a glass bulb only by using cold water. By cooling down the closed, hot glass bulb, the pressure sinks within and water vaporizes at lower pressures when the temperature is cooler.
