Gravitational Sag of various tubes
We have tried to compare the gravitational sag of three identical lengths of the straw material. The Lumina mylar straw, the Stone Kapton straw and the Euclid mylar straw. With the straws supported at both ends, the is slightly more sag in the kapton than either of the mylar straws (pictures above, but very hard to see).
With the straws supported it at one end, the katon straw sags about 2cm below where either of the mylar straws are.
