Here we witness the birth of a T-1000.
What's Actually Happening: 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.

omfg sentient rope
What's Actually Happening: “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.” – suspendersarecool

I CAN BREAK BOTTLES WITH MY MIND, I AM AN X-MEN.
What's Actually Happening: “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.” – GrinningPariah
