This work comes from a residence in Trentino aimed at reflecting on the concept of limit and boundary. The performance starts when the nitrogen comes out of the tank and enters the balloon inflating it regularly, the end time is not certain. The balloon continues to swell while the residence closing party takes place in the next room.
The title is a mathematical limit that calculates the expectation that precedes the burst of the balloon. The operation consists in the sum of the diameter at the volume with the unknown (x) which tends to the time.
