André is always discovering practical things: a mobile phone charger made of lemons or a battery-powered broom, for example. Or a folding machine for t-shirts made of cardboard. Or a rocket for New Year’s Eve that ignites without a flame. Bizarre inventions that are fun and easy to reproduce. Everything works – more or less. André has loads of ideas and tests everything. Sometimes he doesn’t know how to continue, then Mr. Funk helps him out – a professional when it comes to technical knowledge. Together they are an unbeatable team!
