The next time you're stuck at an airport waiting for a delayed flight, instead of turning to your smartphone to pass the time, just make sure this cardboard version of table tennis is one of your carry-on items. In just seconds it can be unfolded and assembled into a working ping-pong table, complete with a cardboard net, cardboard, paddles, and a cardboard scoreboard.

Tennino, as it's called, is recycling at its finest, and at just shy of $70 it's way cheaper than a real regulation-sized table (made of regulation materials). The only thing that's not cardboard is the included yellow foam ball that's dense enough to bounce across stiff cardboard. And while most ping-pong tables were long ago re-purposed for beer pong, unfortunately cardboard and liquids just don't mix, so you'll want to avoid using this for anything other than traditional table tennis.
