Since 30 October, three quiz questions have been asked every Monday as part of the programme. The best quizzers have the chance to take part in the casting for the big final show – “Galileo Top Brain”. And there’s 25,000 euros up for grabs!

At the beginning of October, the two reporters Claire Oelkers and Christoph Karrasch visited us in Linz, where our expert Hans Starl conducted some tests with them. Their task was to estimate at what hailstone size (taking into account the impact speed depending on the size) a 4mm thick window pane would be smashed through.

The programme was broadcast on Monday and can be viewed HERE.

What do you estimate – at what hailstone size will the glass pane be perforated?
