Build a structure using uncooked spaghetti and marshmallows - great as part of a games night
Plenty of spagetti
Give each lodge a large supply of spaghetti and marshmallows, some paper and pens. Give them a few minutes to discuss how and what to build. The object is to build the tallest tower in the time allowed.
Perhaps give a prize to the winners.
[Just a note after running this activity (with apologies to original author for editing!) - this activity is surprisingly messy once the marshmallows get broken up for building so it would be best done on a wipe clean surface. We spent a lot of time cleaning squashed mallow off shoes, carpet etc!
Also, the most cleverly engineered design was narrowly beaten by a Six who shoved a load of materials together at the last minute so we ended up awarding both tallest and best design prizes]
