Tower building.

A team building exercise in all sorts of situations, or a competition, or just for fun.

You could make up a whole backstory of why the tower is being built, such as a signal for help by lost explorers in the rainforest, or you could just build it!

You could set requirements, such as the tower has to be at least as tall as the smallest person in your family,mor has to support the weight of a golf ball, or a small torch, etc.

My favourite materials for tower building are marshmallows and spaghetti, partly because the participants get sticky hands which ups their frustration level ;-)

Newspaper and a limited amount of tape are good - rolled up sheets of newspaper make a surprisingly strong building material.

Art straws, or drinking straws, and a limited amount of tape or blutak work well.

I've always set a time limit for tower building, as well as a limited range of materials, and given it a competitive edge, but it would be quite interesting to see what could be done with no limits at all. I imagine enormous structures could be created!
