I saw these blocks at the dollar store the other day and was inspired. A little hot glue and before you know it, you have a really cool puzzle that is surprisingly hard to solve. Don't believe me, build one!
I'll post a takedown of the black one at the end of the video later, it's a different puzzle for those of you that enjoy this sort of thing.
Oh, and check out #thl it's this new group of homesteaders that have banded together to form a steemit group. I think it could be a force to be reckoned with here shortly.
