By now you've probably seen those Metal Earth foldable models in toy stores and at checkout stands all over the place. They're this generation's flat-packed foam gliders, but as you can see from this incredibly intricate Apollo Lunar Lander model, they require far more patience and skill to assemble.
At just $13 on Amazon you won't feel especially bad if one of the tiny details accidentally snaps during assembly, or if you end up losing all patience and give up on the model before it's complete. It's the journey that matters most here—because even if you don't end up with a finished model, you'll still have the cuts and scars on your fingers to remind you of your efforts.
