The tallest tower + modifications
This activity is well know: split participants into groups of 4-5, give them 1m of scotch tape, some pages from newspapers, scissors. Task: build the tallest tower.
+ they should be able to move the tower at least by [X] m. (you decide) after it’s built, you can provide some paper clips if you want
+ make teams of 4, each 2 pairs should have their left+right hand tied together (2 people connected by 1 left and 1 right hand, so it looks like they have 2 free hands and 1 common); now they really need to collaborate (skills: team building, working with limitations and collaboration)
+ as above – make teams of 4 but now tie hands only of 1 pair in each team; blindfold the other pair in each team (now in each team you have: 1 connected pair, 2 blindfolded people); the connected pair will use scissors and also needs to instruct blindfolded guys; this version is nice, funny and also difficult as team needs to make sure, that blindfolded people are not just standing and waiting for the other pair to do everything (skills: team building, communication, working with limitations, collaboration).
