I gave myself a personal challenge to do a double blow-to-pop while wearing my sexy turquoise and black corset. It's rather tight and restricts my breathing, which makes blowing up balloons a bit more difficult. Still I manage to inflate two 12" blue balloons back and forth simultaneously. I try to get big necks which is a challenge in itself with only one hand for each balloon. Eventually one pops, then I can focus on the other. The pops are always surprising and make me giggle! :)
