Over at Backchannel, Andy Warner's delightful comic about how a naval engineer invented The Slinky.
It's part of a series of "Innovation Comics" that I was excited to commission Andy to create as part of an Intel sponsorship on Medium. "How a Naval Engineer Turned a Torsion Spring into the Slinky"
And don't miss the first in the series, "How A Man and His Dog Invented Velcro!"
