Sempertex balloons are known for their quality and ability to inflate bigger than you expect. But how much bigger? That's what Mariette will find out soon! :) Our challenges are a pleasure for her - just look how passionately she blows these balloons! She even left a big autograph on the blue balloon with her red lipstick! It wouldn't save this loon from popping but still very sweet :)

The second balloon got very tight and popped suddenly when Mariette left the room briefly. The pop is recorded but...yeah.
