Nothing in there on its electrical properties. Can it be cut using a plasma cutter?

While researching a reply, I uncovered USDA Technical Bulletin No. 1413: "Thermal Properties and Heat Transfer Characteristics of Marsh Grapefruit". Please enjoy:

#133I'm not sure "non-cuttable" is the best description, it is cuttable, but it messes the tools
"Cutting resistant" might be a better description, and it is an interesting material regardless
Sounds like it works for applications where you need something to absorb "stopping" energy but without wearing out (too much)

#134What about cicular saw with diamond blade? You can cut cement, ceramics and granite with it... What about demolition hammer or hammer drill?
Looks like a conventional cut off wheel in the video, not a diamond blade.

Yeah, I wanna see what happens when you thump it with a hammer.

I’d say throw it up to the appropriate height. You don’t need exactly 10m and it’ll replicate the drop event perfectly.
Note to grapefruit tossers: Please practice safe science. If you're going to throw an object 10 meters straight up in the air and see how it impacts the ground, you need to not be the ground it impacts, or at the very least your science will be ruined, if not your day as well.

> produces particularly pithy progeny > fantastically fastidious on fruit quality Great alliterations. Great writing all around. This just made my night.
Seconded. This could have been written by Churchill.
Actual Churchill quote would be "My dear you are inedibly bitter, but tomorrow I shall be sober and you will still be inedibly bitter."

I have a 5-6m high grapefruit tree, and they... do not survive the fall. This material sounds cool but I hope it's better than my grapefruit.

Flavor-wise it undoubtedly is.

If it has a keyhole it can be picked, a lock made of diamond wouldn't resist.
> If it has a keyhole it can be picked What if you can't get your picks into the keyhole? I saw a lock that had a tubular key, and an airlock-like mechanism between the place the actual keyhole and the opening for you to insert the key. You would insert the key, and then activate the airlock-like mechanism which would transport the key to the keyhole. There was then a mechanism to rotate the thing that was holding th…

This says nothing about the momentum of the cutting tool. My immediate instinct is: "New non-cuttable bike lock defeated by - Cable Cutters - "
Great engineering regardless, would love to work on a project like this.
