Bubbles in the sky

Since our wedding is outside, on the beach, rice would just litter the beach. I am not the traditional type, so rice was already not in the books. I do love the idea of handing out bubble bottles to our guests to blow into the sky after the ceremony. Since bubbles can be kind of messy, I think it would be good to provide each guest with a drawstring pouch, with one small bottle of bubbles, a napkin, and a note asking each guest to blow bubbles once we walk down the isle as husband and wife, then toss the napkins and bubbles in the trash close by. I want to make sure everything is disposed of, so I will need to make sure someone is around for damage control just in case someone discards it on the beach.
