A new video posted online Sunday shows what happens when LED lights are dunked into a bucket of liquid nitrogen.
The experiment, conducted by YouTuber Drake Anthony and friends, revealed that the color of LED lights and lasers change when significantly cooled with liquid nitrogen.
"Amazing," commented one person on the video-sharing platform.
"This is so cool," echoed another.
Anthony provided a scientific explanation for the phenomenon on his YouTube page.
"This experiment works by utilizing liquid nitrogen to cool the semiconductor to -196ºC, robbing it of much of its thermal energy," Anthony wrote. "This causes the 'bandgap' energy to increase, thereby increasing the emitted photon energy and decreasing the emission wavelength."

At the time of publication, the video had amassed more than 70,000 views.
Anthony's "laser shotgun" attracted a lot of attention earlier this month, with the video showing how it worked being viewed more than 5 million times online.
