What’s the wizardry (science) behind all of these science experiments? Some include proto-visibility, waterbending, uphill waves, and even a lightning hammer.
The possibilities with science are endless. In each gif, you’ll want to ask yourself what exactly is happening.
Aha, maybe you should have paid a little more attention when your freshman science teacher performed this wizardry right in front of your eyes.
Here are 14 awesome examples of science experiments, and an explanation of what’s happening:
The Science: A solar furnace (also sometimes called a Fresnal Mirror) concentrates sun rays into a focal point that can reach up to a temperature of 5,430 ºF, hot enough to melt steel in a couple seconds.
The Science: The rope is being driven on the wheel that it’s placed on at the beginning of the gif. The guy then flicks it off the wheel and it is still spinning when it hits the ground and so it starts moving, much like a tire would if it was spinning and all of a sudden it the ground. But where the tire would just keep moving, the rope does not have that same structure so it just collapses in on itself while it’s rolling.
The Science: They’re polyacrylamide beads which have the same refractive index as the water making them essentially invisible.
The Science: So you start off by hitting the bottle hard on the top. The bottle moves downwards immediately but the water in the bottle doesn’t instantly accelerate to keep up. This creates a near vacuum at the bottom, an extremely low-pressure void which is those “bubbles” you see there.The other poster is right up to that point, but what happens next is even more insidious.
After the bottle stops moving from the initial jolt, the water is ruled by the difference between the pressure in the atmosphere and the utter lack of pressure below it, and moves down very quickly. But since there’s nothing between the water and the bottle to cushion it, not even air, the entire bottle’s worth of water hits the bottom with the pressure of our atmosphere behind it.
Since water is basically incompressible, all that force gets transferred to the bottom of the bottle, an effect known as a water sledgehammer.
The Science: The ball is shot out of an air cannon at the same speed at which the truck is moving causing 0 horizontal velocity meaning it will simply drop straight to the ground.
The Science: A stream of water is exposed to an audio speaker emitting a 24 hz sine wave and shot with a camera that’s recording at 24 frames per second.
The Science: Laminar flow. Basically what’s happening is that the dyed corn syrup is flowing in parallel layers with no crossing of the streams, the low velocity at which it’s flowing (bring turned) allows the layers to slide past each other like playing cards.
Reversing the direction at the same velocity occurs when a fluid flows in parallel layers, with no disruption between the layers allows the layer s to “unlayer” so to speak.
The Science: The viscosity of the liquid is the key part. The effect is like a siphon, where the lower down liquid can transmit (via the viscosity) some of it’s energy to pull the upper part over the rim of the beaker.
The Science: The water in the glass has been cooled down to below freezing point. However, seeing as how it’s been done carefully, in a very clean glass, it’s had no seed for any ice crystals to form, so it continues to jostle around in the liquid state (albeit very unwillingly).
Add the ice-cube, suddenly you have a seed, and because the water it already well below freezing point, it all latches straight onto the growing ice crystal.
The Science: The speaker induces oscillations onto the plate, which then oscillates itself. Depending on the speaker frequency, the plate vibrates in different so called eigenmodes, the shapes you can see.
The Science: The smaller cube is a super-strong magnet that has magnetized the tiny bits of iron oxide in the putty. Once magnetized, the putty is trying to distribute itself as evenly across the cube as possible.
The Science: It’s a thick copper wire. The copper wire has a current running through it which creates a magnetic field. The magnetic field goes through the metal in the center and creates a current through that metal. This current causes a resistance and alas, this resistance generates heat (enough of it to melt the metal, also known as induction heating).
The Science: The acrylic sheet is blasted with electrons, but because the acrylic sheet is a very good insulator, the electrons stay trapped with no place to go, until a nail is gently tapped with the hammer.
The sharp point of the nail opens up a path for the electrons to escape and all the electrons rush along the path of least resistance damaging the acrylic sheet as they go. Viola, you have a lightening sculpture, aka a Lichtenberg figure.
The Science: Since a jar has a finite amount of oxygen, so when you light a fire at the top of the jar the fire will burn through the jar at an increased rate – giving us a wonderful show in the process.
