Rubber Band Engineer
If you like these projects, I encourage you to buy my book, Rubber Band Engineer. It's full of more awesome and original projects crafted from household hardware. You can find it wherever books are sold.
Duct Tape Engineer
I'm also working on an upcoming book, Duct Tape Engineer, a collection of big, bigger, and epic-sized duct tape projects. Please contact me if you are interested in reviewing or promoting the book in late 2016.
