This is a short episode about a puzzle that I got for my birthday from my in-laws. I gave the puzzle to two of my children to solve after I'd taken a crack at it. It was amusing to see see how and old engineer thought about the problem compared with young ones. Pictures of the puzzle are attached. The object is to get one ball in each notch at the end of the block at the same time.

Well done on the audio description of the puzzle. I had an almost perfect picture in my head of it before seeing the pictures. That's not an easy thing to do.

The story itself was also great. One of the most fun shows to listen too.

Glad you liked it

Very glad to hear that the puzzle description was clear. This was my biggest worry about the podcast: that it would be hard to imagine what was happening! Thanks for the feedback!

A most interesting show

Thanks for this. It really made me sit and think. I arrived at the 'true' solution just before you mentioned it, which is probably more coincidence than anything else - I'm usually poor at doing things like this!

Excellent show

This show was great. The magnet thing was hilarious, it seems that kids always come up with those incredibly simple solutions. Very reaffirming and entertaining. Thanks for sharing!
