This is so cool! Here’s a video that shows an ink drop getting hit, all of a sudden, by a laser. We can see what happens when the laser pulse is out of focus, and the drop is pushed. And we can see the drop get obliterated when it’s hit with a focused laser.
Not much to say here, since the video explains it all. An ink drop gets hit with a laser when the laser isn’t focused, and it’s pushed into a gentle umbrella shape. When it gets hit with a focused laser, it explodes like a jellyfish that just got hit with a cannonball.
And at the end we see the ink drop turn to plasma and create its own light.
