As the bubble rises, the surrounding water pressure decreases and the air inside the bubble expands. The bubble eventually splits in half when it expands too much.

Nudibranchs are a group of soft-bodied, marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colors and striking forms, and they have been given colorful nicknames to match, such as "clown," "marigold," "splendid," "dancer," "dragon," or "sea rabbit." Currently, about 3,000 valid species of nudibranchs are known.

⁠
"Each gas has a characteristic breakdown voltage and emission spectrum - note that Nitrogen has the highest breakdown voltage and only glows when very near the coil where the field is most intense whereas Neon and Helium have the lowest breakdown voltage and begin to glow many centimeters away from the coil."⁠
⁠
"The color of each gas is due to a mix of the colors emitted from electron energy transitions specific to each element - the basis of spectroscopy. The Krypton tube also exhibits interesting oscillations with this particular Tesla coil."
