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!

10. Slovenia - Technical Chain Reaction
Hello from Slovenia!
This year we have to admit it was hard to choose from all the toys we prepared for the chain reaction. And not all of them could fit in. We gave our best in a very short time. Enjoy!
Sending you greetings.

4. Finland - Technical chain reaction - Dreaming at school
Hello all!
Here is the chain reaction from Finland!
Does it ever happen in your classes, that the pupils are tired and it's hard to concentrate on mathematics, especially if it's the last lesson of the day?
But luckily you can fall asleep and dream... of a chain reaction!
We hope you'll like our video! We had a lof of fun with it!
Good luck everyone!

Slovenia - Human Chain Reaction
Better late than never 🫣. Our group exists of 18 very nice "little humans", age 6 - 7 YO, eager to play indoor and also outdoors. We are hardly waiting to continue with our work on technical chain reaction.
I hope you are going to enjoy working on different paths as much as we are going to.
Wish you all the best and sending you best wishes from Slovenia!

Spain - Human Chain Reaction
Hi everybody!
This year, our class chose a special theme to connect all our projects: Charlie and the Chocolate Factory. But with a twist. We turned it into our own Factory of Emotions, where every idea and little character comes to life. We love that this eTwinning project is now part of our story.
We’re really happy to be here once again!
Greetings from Lanzarote!
