Team of the Waterjet Channel on YouTube recently found an enhydro agate that was 2 million years old and it had water trapped inside. So the team decide to break it open and have one of their members, Mitchell, taste the 2-million-year-old water. One of the dangers here is that there’s no guarantee the water from the agate is safe to drink. In fact, the guys over at Boing Boing point out, “…enhydro agates rarely contain pure water. They often also contain quartz microcrystals, debris, or petroleum, and it all depends on the conditions under which they were formed.” The team also collected culture swabs of Mitchell’s tongue, the rock water, and a gas pump that Mitchell had licked in a past episode to analyze and compare after a week. Check out the video for full results.
