Special thanks to the experts and collaborators who made this video possible:

Professor Todd Blackledge and the Blackledge Spider Lab at the University of Akron, for welcoming us into the lab, walking us through how spiders make and use silk, and letting us put the real material to the test.

Jon Rice and the team at Kraig Biocraft Laboratories, for opening their doors, sharing their transgenic silk, patiently explaining how their engineered silkworms work, and helping make the spider-silk swing possible.

Professors Keiji Numata, Chris Holland, Sara Goodacre and Greg Holland, for generously sharing their time and expertise in our research conversations helping us understand the extraordinary diversity of spider silks, how they are spun, and how structure, water and chemistry shape their properties.

Professors Ingi Agnarsson and Thomas Scheibel, for their guidance that helped sharpen our explanation.
