Oddly satisfying clip of three balls of molten glass getting blown together into a huge sphere.

The clip, filmed on October 14 in Rochester, New York, shows the three balls of glass being connected while being handblown.

"Three bubbles unite into an almost perfect sphere with a rainbow thin membrane! The balance of breaths and heat in this one is pretty unique!" the filmer, a glass artist from Mad Hot Glass, wrote on social media.
