I threw out a 20" 90's era Sony with built in VCR.
I flung it in an empty dumpster. I heard the biggest boom and it blew the back of the set. I NEVER saw a CRT implode like that. Back in the repair shop days, we junked a ton of sets and only got a small pffttt when we necked the tube.

Ditto on that. As a (reckless) teen I hauled a 32" Color CRT from an early 90s Toshiba television, with the help of friends, down to a bridge nearby which golf carts would use to drive over the river and dropped it off onto the sand below. It was a good 20 foot drop. The implosion sounded like a cannon firing and shook that sturdy bridge pretty well. Of what remained there was a shadow mask, yoke, and gun inside of a good sized crater of debris.

The potential is definitely there.

The older tubes made before the various "integral implosion protection" schemes are certainly much more energetic as a rule.

Most of the modern tubes I have disposed of were pretty unspectacular. Just a quick hiss when the neck was broken off, even the big ones over 25". The most powerful bang I remember was a lowly 10BP4 that I chucked into an empty dumpster behind the shop I worked at. Sounded like an M-80 firecracker going off, and threw pieces of glass up higher than the building.

Panasonic 32", I think it was called a "Tau". Put it in the garbage truck with the face down. They then compacted the load. It sounded like a bomb inside the truck. If you want to make them implode violently, hurl a brick at the angled side. They make quite a mess.
