[QUOTE="Binastro, post: 3345490, member: 111403"] It seems that spider silk might be 0.001 to 0.004mm thick and fine human hair about 0.04mm. This is from internet sources, so I don't know if accurate. I didn't know, but apparently spider silk can stretch up to 5x without breaking. Spiders can combine silks for extra strength, so I don't know if my cross hairs are one strand or several. [/QUOTE]
