Researchers at Rothamsted Research redesigned the model to allow for elasticity and flexibility in the spider's dragline, its most sturdy line of silk used for moving about and snagging prey.

Apparently these plastic spools flip open and shut to dispense and protect the solder wick; just take out the wick and wrap your earbuds around the spool instead.

A new study reveals that dragline silk, the stuff spiders use to rappel, has a molecular structure that makes it resilient to twisting.
