The weather did not cooperate with us on the day of the fourth fight in Ekaterinburg. In the rain and through streets characterized through huge puddles the team made its way to the Ural Federal University, the venue of the IYPT.
In a fight of four the report was Switzerland’s first task. Sweden challenged the team to problem number 5; Ultrahydrophobic Water. Once again it was Joonas’ time to shine. Standing in front of the jury confidently, they were immediately convinced of his theory about the small droplet; scoring 7.5 points.
After a well-deserved break as observer, it was Switzerland’s turn to review problem number 8, Magnetic Train. It was the captain’s, Marc’s, turn to review a very theoretical report and discussion by Croatia and Slovakia. Marc secured the team 7 points, putting them into a good position to win the fight.
In Switzerland’s last challenge Marc challenged Slovakia to problem number 10, Light Rings. Émilie was ready for her first opposition. With the opponent she discussed the relevance of the water jet dynamics, which he largely ignored in his report. With another 6.38 points in the discussion, Switzerland’s future at the IYPT is bright.
After this strong fight, Switzerland keeps its third place and is more than 10 points ahead of the fourth place. A place in the final is not secure yet, but it is very realistic. In the fifth fight problem number 10, Light Rings, will be presented.
