More iteration and production...

Last time, I shared about Untangled and how my students created, designed and printed a device to untie shoelaces.  They redesigned it based on timed trials and made it thinner, even adding an 'ergonomic' handle to it.  While the original was too thick and cumbersome, the redesign was too thin and flimsy.  In the meantime, however, they retimed themselves using the redesign and halved the amount of time it took them to untie difficult-to-undo double-knotted laces.  Not too bad...
