You might not have a puzzle coffee or puzzle coffee tables around, but that doesn’t mean you can’t build one yourself.
The best way to do it is to go out and buy a used one.
Then, you can modify the layout, add extra coffee, add the spiral cups, and more.
This post shows you how to make your own, using a variety of tools, including a template, cutlery, a hacksaw, and a bit of hand sawing.
You can find more tutorials on how to build puzzles, puzzles tables, and other items on the TED blog.
