Another "X" Puzzle

Thats cool !! Do the pins travel freely up & down ? If so what would the size of the pins be & the size of the holes that they travel in ?

First time I’ve seen one of these. So the trick is to figure out which end-cap to pull first, right?
Pretty cool

Actually, the end-caps don’t come off—I glued them on after the holes were drilled and the pins were inserted. And, yes, all four pins travel freely—they’re slightly smaller than the holes. (I drilled 3/8” diam holes and sanded a 3/8 diam oak dowel till it slid easily.) The idea of the puzzle is to push the pins back in each of the two blocks—and put the blocks together like shown in the first photo. Next, shake the whole thing. The pins will slide around in the holes so the two halves won’t separate—then hand it to someone and ask them to take it apart. It may take them a while to figure it out—and it’s embarrassingly simple to solve.
