show a pix of you on a roller coaster
I already uploaded my pic to another dare. :\ http://www.makeadare.com/video/upload-good-picture-yourself-69
Easy just go on a roller coaster and film your reaction through out the whole ride. the bigger the roller coaster the better!
Go into your favorite fast food place wearing a pair of roller blades and order food. See if anyone notices and says anything to you but you have to act as if you don't even have them on when you go in and order.hahaha
It burns like hell, so have fun :D
