US climatologist Peter Neff is with a team in Antarctica drilling holes in ice sheets to study the gases trapped inside glaciers. For this, narrow and deep holes are made, removing blocks from the material for analysis. However, a video posted on Neff's Twitter drew attention to a curious phenomenon: the sound produced by a piece of ice hitting the bottom of a 90-meter hurricane.

Certainly, it will be unlike anything you can expect. Doubt? Then hit play and tell us if this is what you expected to hear:

???? Sound ON ????

When #science is done, it's fun to drop ice down 90 m deep borehole in an #Antarctic ???? #glacier ?? So satisfying when it hits the bottom.

Peter Neff joked about the situation by saying that the holes are blue portals that produce an unexpected and fascinating sound. It resembles a laser shot that we often see in "Star Wars" movies, for example.

The phenomenon was recorded in the Taylor Glacier, where the team is removing blocks for analysis - don't worry, as the holes quickly close naturally due to snowfall and glacier movement itself. These blocks differ from “normal” ice, made in the laboratory or in your home's refrigerator, by compressing snowflakes that are therefore very airy. The result is ice with bubbles, as you can see below:

Difference between laboratory ice and glacier interior

Another thing is that removing pieces of ice from such deep layers is like going back to the past, including the last Ice Age 20, 000 years ago. Now, if you were intrigued by the laser sound, the team from Neff and the University of Rochester in New York have also released another equally mesmerizing and fascinating video.

Lest you think we were able to control our glee while putting #Antarctic #glacier ice back in the borehole it came from ... pic.twitter.com/hjLyZe8Bms
