Water drop burrowing into heated glass power (speed x5)
Because this glass powder is much hotter than water's boiling point, the water droplet vaporizes as it touches the surface. But as the vapor moves upwards, it carries some of the powder away with it, creating an impression. Simultaneously, the droplet's vaporization causes it to vibrate, freeing more powder so the droplet can dig deeper. Once all the water vaporizes, all that's left is a small crater
