A 
great way to pass the time when it's negative 10 outside - build a 1580 piece 3D puzzle! I had seen this on Amazon months ago and thought I might try it. Then when I tried to buy it, I saw that the company Wrebbit had been bought out by Hasbro 2 yrs ago, and they were discontinuing all of their 3D puzzles. You can't find them in stores anymore, so I got this one on eBay. You actually build it in two parts and then push the two together.
