Agatha, Sylvie, Chavez and Kyle Sichi would conduct the experiment Carter, Iron Axe, Barov and all the other witches of the Witch Union were also required by Roland to coreat practical and educational significance The fifth laboratory was chosen for this event, given that it was the largest lab and had enough space for the two dozen people

Considering the experiment was the first of its kind, Roland had built a tower-shaped vessel which was only as tall as a iant fractionation vessel The inside of the vessel was divided into three parts The air would enter the vessel through the bottoh the two parts above

Before separating the air, Roland gave the to happen and putting forward a few questions for them to think about and try to answer It was a trick frequently used by cheue their students and enhance the effects of the lesson

" theoretically, when Agatha cools down the vessel and brings down its internal teradually be condensed into liquid, and drip down into the bottoh the holes in the plate So when you see liquid at the bottom, please let us know"

Roland explained to Sylvie in detail, because no one except her could directly see into the vessel and describe the changes happening inside

Sylvie nodded somewhat skeptically, "Will I really see liquid appear? Will it not be only the water vapor inside the vessel?"

"No, it's different The liquefied air is light blue, completely different from water vapor" Roland shook his head and explained further, "Plus, at that temperature, the water vapor will be solidified into ice crystals long before the air" Then he et started"

"Wait Do we not have to plug up the hole in the vessel's bottom now?" she asked

"Block it up later Otherwise, the vessel won't have enough air inside to bring about significant changes" As this was only an experiment, he chose the easiest way for air intake—when the air temperature inside the vessel was rapidly lowered, the internal pressure would fall, and thereby draw the air into the vessel In y and the cool air would run off continuously Therefore, this cooling method was considered inefficient and rarely applied in practice However, Agatha'sdown the vessel's te Roland the trouble to prepare an air puatha took a deep breath and pressed her hands onto the fractionation vessel

About half asounds could be clearly heard as the air was rapidly passing through the air intake pipe White frost could be seen by the naked eye around the pipe hole, and its area gradually expanded—the water in the air nearby was quickly solidified, and then adhered to the vessel Anna turned her Blackfire into threads to clean up these continuously thickening ice crystals

"I see so on the plate, but there's more white frost inside" Sylvie said in an amazement a moment later

"The white frost may be the solidified water vapor or the crystallized carbon dioxide," explained Roland "Considering that there's only a small portion of carbon dioxide in the air, most of it should be solidified water vapor"
