TV contribution: What is the reason for noise in water boiling?


Boiling water happens every day in the kitchen. But have you ever questioned why there is so much noise generated before the water actually boils?

A little TV contribution for kids-TV (KIKA) will be shown on the 15.02 at 19:25 presenting our experimental videos of bubble growth and collapse during boiling.

The HeatQuiz development continues (Fellowship for Digital Teaching)

The development of the HeatQuiz is now supported the the „Fellowship for digital teaching“ of the NRW-Stifterverband. With a financial volume of 50,000€ we are able to bring the teaching game to a new level.

In addition, we are proud to present the APP now also for iOS. It took some time to get it running but now it works!!
