If this turns out to not be true, and just said for the amusement of thinking of all the people jiggling their keys at insects, it reminds me of something a friend in high-school said to me:

"If you peel a banana, take a bite off the top, and then poke your index finger in to the middle of it, it will split in to perfect thirds".

Upon trying this, I discovered it was not true, and my friend just wanted to see me stick my finger in a banana...

I never tried (yet) but a quick search reveals a lot of people filming the "banana split in thirds" action, e.g. https://youtu.be/NoGXTXsamt4?si=ANNTdtcu1trOdQXP

It's still technically possible it's a hoax but, boy, that's a lot of effort to provide fake content to support the hoax.

Nice. Maybe GP got the wrong end, or it is a test of ripeness, or perhaps 'bite off the end' ruined it (it at least didn't seem to be necessary in the linked video).

Actually, I do this when making a banana split. Cut a piece off the top and then slowly press the banana into thirds. Then, lower the banana, with the bottom part of the banana still intact, into a tall glass. Smoother with cream, ice cream and/or syrup. Makes for a solid banana split.

Ha, no way!

All this time I thought this was him being silly!

(For the record, the banana did NOT split nicely)

A banana does actually third itself when split.

I'm still going to shake my keys at the next swarm I passby.

funnily my friend just discovered that you can split it into thirds a few day ago and now does it whenever he eats a banana

"If you hand is larger than your face . . . "

Too bad it's winter and I'll probably forget this before I have a chance to!
