The European Chain reaction is a European Quality Label winning eTwinning project that was first organised in 2011. The project is a contest and a European collaboration between primary schools from as many as possible European countries. In the contest primary schools compete for the honour and a nice trophy: Which country builds and films the most astonishing and creative Rube Goldberg / Robert Storm Petersen chain reaction? The competing children are the only judges in this game!

The human chain Reaction from FINLAND!
Hello all!
Here is the human chain reaction from Finland! Our school's fourth graders will represent Finland this year, classes 4A and 4B. They are 10 years old.

Good luck to everybody! And Merry Christmas!
