We could do a massive collage http://www.edinburgh.gov.uk/galleries/g ... e_of_frogs
People throughout the day would just randomly cut and get new stuff on the collage.
We could do the Blender Russian Roulette.
Random ingredients, blended together.
If you guess them all we'll give you. Erm. A badge. Good job.
We could do the drawing-doodling-scribbling-therapy.
I love customizing/vandalizing colouring books, got one today, 100 pages for a pound, dead easy and lots of fun.
We could have a free-shop in there.
We could have a wall of useless facts. People would write useless world trivia in there and, by the end of the day, the least useful fact would win and we'll give you. Uh. Yeah. A badge. Or two. Keep up the good work.
We could have Instant Impersonation Booth. We'll provide some random pieces of clothing, make-up, other random accessories and you would have 5 minutes to become & convince us they are someone we all know. We could do it as a contest with two people doing it simultaneously competing with each other or just take photos and chose a winner by the end of the day. We definitely need to make those badges.
I don't know.
