If timed correctly, explosions can break the blocks when it's pushed/pulled by piston (during the animation).
How to reproduce:
Create an observer clock and connect it to a sticky piston.
Place a netherite block/ancient debris in front of the piston.
Ignited lots of TNTs.
The block is blownup and dropped as an item.
