Basically, that news post says it all. There was really nothing to it. We brought our robot to the front entrance of our school. Set up two tables with tools and miscellaneous team 1257 stuff, and started collecting money

.
Personally, I had thought it wasn't a terribly great idea, but I had not counted on one thing, one
very sociable freshman working the crowd bringing people over to the table. This guy probably supplied more than half our sales by going up to parents, introducing himself and briefly explaining what the fundraiser was and then walking them over to the table. A lot of parents thought it was a cute idea and had a hard time deciding which tool to pick and what to write on it.
It may not work for any team because we have a very close-knit, supportive school. The fact that its a magnet school that focuses on math, science, and technology didn't hurt either. Regardless, it takes almost no effort to run, so any time you can get a large group of people with money together, try it out.
