Exobotics! This is What Happens When You Run Water Through a 24hz Sine Wave. What!?
How is this even possible? Because science, my friends. Brusspup’s (previously) latest video explores what happens when a stream of water is exposed to an audio speaker producing a loud 24hz sine wave. If I understand correctly the camera frame rate has been adjusted to the match the vibration of the air (so, 24fps) thus creating … magic zigzagging water. Or something. Run the rubber hose down past the speaker so that the hose touches the speaker. Brusspup did a similar experiment last year where it looked as if the water was flowing in reverse. Physics Engine. Physaxe is a 2D Rigid Body Physics engine written in Haxe.

How big is space? Big questions demand big answers.
And here at Future we have a hard time thinking of a question bigger than: how big is space? So, we set about trying to illustrate it. The resulting picture is so large that we could not squeeze it all on to one image in Photoshop. Instead, we had to create several sections and stitch them together for you. Printed out, the graphic spans 27 pages of A4 paper. But even at this size we only managed to get to the edge of our Solar System – known as the heliosphere. Yet even within this relatively small corner of space, there is a lot packed in there.
Laser Pointer. A DC Current Transformer" Water has properties that are positively electrifying! Most people certainly understand how important water is for our survival, but we often overlook how weird it can be.
I can compile a short, though not exhaustive, list off the top of my head: Water is less dense in solid form (ice) than in liquid form. Ice cubes float, and ice forms at the top of lakes, protecting the fish and other organisms below from the cold. Water is one of only a handful of substances for which this is true.Water can be supercooled, and “instantly” frozen. Very pure water can have its temperature lowered below the freezing point — supercooled — while remaining a liquid. Equally odd, but even less known, is the curious ability to bend a stream of water with static electricity. The rod is made of glass, and is what is generally known as a friction rod. Why is water so strongly attracted to static electricity? To begin our explanation, we need to look at the molecular structure of water.
How does this affect the electrical properties of water?
