[Day 1] Let’s go to the far north!

For the second activity, head to the Steindalsbreen in Tromso, Norway. Here we will get to know the second glacier in the project and prepare it for the project. Again it is about interesting phenomena and experiments.
There was enough time on the flight for an experiment on air pressure: An empty water bottle is opened and closed again at flight altitude. Looking again at the bottle after landing, you can see very clearly that the bottle is dented. This is due to the change in air pressure. At cruising altitude, the air pressure in the cabin is like that of a 3,000 meter high mountain. On landing, the air pressure rises to normal levels, squeezing the bottle.
