I found a lazy way to do this. I put a jacket on an IV pole and hid behind it and used my hand to start the game. After the game started I ducked behind a couch behind me so the camera wouldn't see me go off screen. The jacket stayed pink and the game played all the way through. If you do not have an IV pole (I work at a clinic) I bet a coat rack or maybe even a little fake house tree or plant would work. Also a tall oscillating house fan would probably work great. Be creative and try out some different stuff and let us know what you used in the comments.
EDIT: I put a vacuum cleaner in front of the camera and started the game. I leaned over and shook it until it stayed pink.
Using this method you could get hundreds of gamerscore in the game without ever playing. Here are other achievements you could get using this method.
