I have been following this product for years - since late 2005 when it was featured in Popular Science for its innovation. They are finally available online. It's colored bubbles!
Right now, they only have pink and blue, but I think that when they have more colors, it could be wicked cute to use them (you can buy bulk for a bubble machine) for recruitment or bid day. Of course, if one of your colors is pink or blue, or in DG's case, both, you could totally use them now!
