“Licht an, Licht aus” Exhibition

The Rubies’ faces lit up during our visit to the “Licht an, Licht aus” exhibition in Kindermuseum. There, we discovered what a driving force light is as we powered solar-panelled cars just by shining a torch at them. Some were able to decipher Morse code messages or powered light bulbs just by pedalling fast. We have also learnt about how electricity is produced and how to build an electrical circuit. You could say that the Rubies have become very switched on!
