Hi everyone:

I propose two new experiments for the balloon flight:

A) The effect of emptiness in a sandwich structure.
B) The effect of low temperatures in a bolted joint.

In order to perform these experiments, we must investigate WHICH ARE THE ATMOSPHERE CONDITIONS AT 30.000 m.

Spanish: les propongo dos nuevos experimentos para el globo: como se comportan las estructuras tipo sandwich y las juntas atornilladas. Investiguen que fenómenos se producen al borde del espacio.
