I am SO GLAD they received the money to do this research! Why would you research UFOs when you can do THIS?! Into how many pieces does a balloon burst? Date: November 2, 2015
Source: CNRS (Délégation Paris Michel-Ange)
Summary: A moderately inflated rubber balloon pricked with a needle bursts into two large fragments. However, if you inflate it until it bursts spontaneously, you get dozens of shreds, new research shows.
The two explosion mechanisms of a rubber balloon. Top line: opening mechanism of a moderately inflated balloon. A crack propagates across the membrane, finally splitting it into two. Bottom line: a highly tensed balloon bursts into a large number of long shreds. The time interval between each image is 0.3 ms. Credit: ©Sébastien Moulinet
Now, Sébastien Moulinet and Mokhtar Adda-Bedia at the Laboratoire de Physique Statistique (CNRS/UPMC/ENS/Université Paris Diderot) have explained this phenomenon: when a crack propagating across the surface of a balloon reaches a critical speed, it becomes unstable and splits into two new cracks.
It is this mechanism of proliferating cracks that causes the balloon to burst into shreds. The work, published in Physical Review Letters, sheds light on the fragmentation processes in materials subjected to impacts or explosions.

Oh they've spent money on stranger things than that In the name of science of course.

Wow I have no more questions, the universe has been solved. Thank god for science.

Since they think all UFOs are either swamp gas or weather balloons they probably think that was UFO research.
