For my daughter's 12th birthday, we all went to the mall.  I broke the eight girls into two groups. I got different ideas from different postings here.  I already printed the list before getting there.  I had the girls choose a number between one and four. What ever their number was they choose, is the number they were.  I gave the rules of they had one hour to complete the list and meet back. Some of the things on the list were like Girl 1-have your picture taken with a bra over your clothes, girl2 have your picture taken laying on a bed, girl 3 have your picture take with someone eating ice cream, girl 4 have your pic taken wearing a red hat.  The teams were given $10 and a list, they had to buy things--something you can wear, something with smell, something purple, etc. I gave them like five things like that they had to purchase. While we sat and had ice cream, the pics were being developed at the one hour photo in the mall.  When the pics were done, we sat and went through the photos, I got twin prints and let the girls pick and choose what pics they wanted from the second print.  Then, the items they bought with the $10, they got to choose what they wanted from that. It was a lot of fun. CHeap idea too.  I think I spent about $40 in all!! No clean up!!  I loved it. The girls all raved about how cool it was!!! What a great day we had!
