The "Levitating" Slinky: The slinky is simply a spring. When a spring is stretched, tension tries to pull it back together towards a collapsed state. The spring’s tension is occurring mostly symmetrically, so it pulls all ends towards the center. When dropped vertically, the bottom end is trying to fall down, but tension acts in the opposite direction, so the bottom of the spring remains stationary. Meanwhile, the top end is collapsing due to gravity and tension. It's not until the rest of the spring hits the bottom of the spring, eliminating the tension that had counteracted gravity, that the slinky finally collapses and falls to the ground. #science #physics #slowmotion #GIF Source: Adam Shomsky https://www.youtube.com/watch?v=8UimHnsWSBc

Fainting Goats: Fainting goats, also known as myotonic goats, Tennessee stiff-legs, nervous goats, and fall-down goats, aren't simply weak of heart or abnormally prone to fright. In fact, fainting goats don't actually faint or lose consciousness at all during these episodes. Due to a congenital medical condition known as myotonia congenita, the goat's muscles tense up when the animal is startled and don't immediately relax. This happens because myotonia congenita affects a particular gene called Choloride Channel 1 (CLCN1). This gene is involved in the production and regulation of proteins, which are vital to the flexing and relaxing of skeletal muscles. Positively charged sodium ions relay the brain's message for the muscle cells to contract. Negatively charged chloride ions, which CLCN1 affects, tell the muscle cells to relax. Myotonia congenita results in an abnormal channel of chloride ions, which throws this relationship out of balance. The muscle cells wind up with more than enough sodium but not enough chloride, which causes abnormal repetitive electrical signals from the brain, such as those associated with being startled, to result in stiffness. #science #nature #biology #goats #GIF
