Explanation of droplet explosion
Swiss high school students are world champions of physics
Five Swiss high school students won the gold medal at the World Physics Championships in Timisoara, Romania. They defeated Poland and Singapore.
The five students presented their solution to the “droplet explosion” problem at the International Young Physicists Championship (IYPT). It comes down to describing the phenomenon that a drop of a water mixture on the surface of an oily liquid can break up into smaller droplets.
The solution presented by Jan Kamm (Kelchberg ZH), Anya Christina Deauville (Forch ZH), David Fankhauser (Bar ZG), Chingge Ho (Zurich) and Joel Tan (Outenbach ZH) convinced the jury the most, allowing Switzerland to victory over Poland and Singapore. On Tuesday, the Pro IYPT-CH Association announced its victory.
Prior to that, the team spent more than a year developing solutions to 17 physical problems. With these solutions, the five students initially triumphed over the national competitors. In the international tournament, their results and conclusions were critically questioned by the competing teams in the discussion. The achievements were also ranked by a specialized jury. This qualifies them for the final against Poland and Singapore.
In the tournament, teams from about 30 countries meet against each other. Each country is represented by five students. (SDA)
