How Lili recharged her mobile in Austria

In Austria I had to charge my mobile. The pupils of 2a had the idea to produce electricity with special “Power-shoes”. There is a thermoelectric module in the sole of the shoes. While the children are dancing the difference between the temperature of the hot feet and the cool floor generates electricity. The bigger the difference, the more energy you get. The shoes/boots should be made of plastic or rubber because inside them you sweat a lot.
After dancing my mobile was reloaded and I could call my family in France.

I told them how we celebrated Christmas in Austria and that I'm feeling fine here.
