Slow the Flow partnered with the MLS team, Real Salt Lake, for some in-stadium messaging. Everyone expected posters, I gave them a memorable experience that put water and grass right in people's faces on game day.
RSL liked the water fountains so much they invited us back the next year. The data show that men are much more likely to be in charge of sprinkler timers, so we put the message right in their faces again. We found some urinal cakes with a grass-like texture for the men to "interact" with (the green color was off though).
After years of politely suggesting they let us update their logo, they finally let me.
