Veritasium’s new video has an awesome demonstration featuring acoustics, standing waves, and combustion. It’s a two-dimensional take on the classic Rubens’ tube concept in which flammable gas is introduced into a chamber with a series of holes drilled across the top. Igniting the gas produces an array of flames, which is not especially interesting in itself, until a sound is added. When a note is played in the tube, the gas inside vibrates and, with the right geometry and frequency, can resonate, forming standing waves. The motion of the gas and the shape of the acoustic waves is visible in the flames. Extended into two-dimensions, this creates some very cool effects.

“Our relationships are our sacred responsibilities, for they are the framework within which life is lived. They show us where we have more learning and loving to do. Our interactions with others call up the disabling beliefs and negative patterns of behavior we need to release—the cynicism, anger, resentment, and jealousy that block love’s flow. Our relationships are our mirrors; they reflect where we are in consciousness. And if we are willing to face the truth about ourselves, our relationships offer the lessons that lead to our greatest transformation.”- Susan Taylor
7 shot iced Americano.
Should just be called an “America”.
Who the fuck needs seven shots?
If you spend too much time thinking about a thing,
you’ll never get it done.
