Advice of the day:

Once you have installed the PhyPhox app, start it. You will find a "+" in the top right-hand corner. If you click on it, you can add the configuration for today's experiment using the QR code and get started. If you don't have a cable elevator nearby, you can recreate the situation with a yoghurt pot, 1-2 m of parcel string and the edge of a table. You will then have to listen carefully, as the cell phone does not fit into the yoghurt pot.
