Katja and Zuzu are presenting the all new ClubSteffi Balloon, printed with our fresh new logo. The one they've picked for this outdoor sitpop test, is a BelBal 24" in Cobalt Blue. The task is, every girl blows it up a little and then sits on it, without popping it.  Turns out, this balloon is pretty tough and hard to pop, even outdoors - but the girls will succeed.
