I was cruising the TV and I came across the Beat The Clock TV show from 1950s. There was a challenge That looked like this:Two small ballsEach on its own 18" string suspended from a wooden barThe balls were 18" apart.You had to put 2 smoking pipe in your mouthYou couldn't use your hands after you put the pipes in your mouth.The ball rested on top of the hole, but did not go in.You had to get one ball in each of the smoking pipesHow do you do it?It wasn't solved on the show I watched.Now, if you get the first ball in and then try for the second, the ark of first ball means you couldn't get to the bottom of the second ball to put it in the pipe.------If you know another site that solves these things; post it here.
