This puzzle will test your spacial ability. The goal is to remove the tetrahedron (triangular pyramid) from the cage. It’s really pretty straight forward if you paid attention in geometry. So, can you figure it out from the pictures? If not, refer to this video:

Those puzzles were why it took me so long to get back into woodworking. My 7th grade Woodshop teacher was really hard on my because I couldn’t not hammer a nail straight but I could solve all of these puzzles he built. Turned me off from woodworking for 20 years.

Love the puzzle and love LumberJocks. Thanks for posting.

This is a very nice puzzle and is a great eye catcher and conversation piece.

Thanks. I like how it looks but it isn’t very challenging to solve. Most people solve it within a few minutes.
