Useful how-to advice, such as drilling a hole in a ceramic pot without shattering it.
Then, after carefully drilling a hole into the crystals' walls and removing the few microlitres of fluid from each inclusion, the researchers began testing their samples for life.
People drilling the hole with a giant rig were just able to pull it out of the way and get to safety when the steam exploded and dug a crater that's more than 100 feet deep and about as wide.
