Me watching that in 2019: "Wow, it disappeared!" Me watching in 2024: "That's like $100 worth of vegetable oil."

It ain't oil, its glycerin. Its thick enough that it refract light rays away, not allowing the beaker inside to be seen.

The phenomenon where Pyrex glass seems to "disappear" in vegetable oil is based on the principle of refraction, which is how light bends when it passes through different materials. Every material has a refractive index, a number that describes how much it bends light. When light travels from air (with a refractive index of around 1) into glass (which has a refractive index of about 1.47), the light bends, making the glass visible to our eyes. In the case of Pyrex and vegetable oil, both materials have nearly the same refractive index, around 1.47. When you place Pyrex glass in vegetable oil, light passing through both substances doesn't bend noticeably because the light "sees" the two materials as optically similar. As a result, there’s little to no difference in the way the light travels through them, making the glass seem to disappear. This is why the glass appears invisible: our eyes rely on light bending or scattering to detect edges and boundaries between objects and materials. Since the refractive indices match, no significant refraction occurs, and the boundary between the glass and oil becomes nearly impossible to see, giving the illusion that the Pyrex has vanished.

Disappearing borosilicate glass in oil 😲 Borosilicate glass and vegetable oil have the same refractive index of light, so when the glass is immersed in water, it's like it dissolves into the oil.

Fresnel reflection coefficient: R = |(n₁ − n₂)/(n₁ + n₂)|² Pyrex rod (n≈1.474) dropped into glycerin (n≈1.473). Instantly R collapses to zero. No reflection. No interface. The glass simply ceases to exist optically—light passes straight through as if the boundary was never there. Not magic. Not editing. Just Maxwell’s equations enforcing perfect index match. This is why immersion oil, AR coatings, and optical fibers work.

To be very clear we can use a mass driver to mine the moon of materials to make Lunar Glass. Formed in zero G and heated with parabolic mirrors the glass can become stronger than Earth Steel. One could produce a glass L5 Colony with robust protection. Artistic license:

‘Allah is the Light of the heavens and the earth. The example of His light is like a niche within which is a lamp, the lamp is within glass, the glass as if it were a brilliant star, lit from a blessed olive tree, neither of the east nor of the west, whose oil would almost glow even if untouched by fire. Light upon light. Allah guides to His light whom He wills. And Allah presents examples for the people, and Allah is Knowing of all things.’ 📖 Surah An-Nur — Ayah 24:35

In one area of Kolkata, these same people beat up a Muslim vegetable seller yesterday. They assaulted the vegetable seller by calling him a "Bangladeshi". (The vegetable seller had voted in this assembly election). These are the 'Kattar' Hindus of the Saffron Ecosystem 🤦‍♀️😂 #Kolkata #WestBengal

The Oil That's Showing Up In "Healthy Foods." Rapeseed Oil Is Canola Oil, Highly Processed Toxic Lubricant Oil Never Meant For Human Consumption. Seed Oils Have A Half Life Of 680 Days. If You Stop Consuming Seed Oils Today, It takes about six years to replace 95% of the Linoleic Acid in your body with healthy fats. Vegetable Oil consumption has increased 329%. The Standard diet now accounts 30% of calories coming from Seed Oils. The same rapid increase is seen in chronic metabolic disease in both physical illness & mental illness. Canola oil (aka rapeseed oil) Corn oil Cottonseed Grapeseed oil Soybean oil Sunflower oil Safflower oil Rice bran oil Peanut oil 85% of store bought Olive Oil & Avocado Oil is mixed with Seed Oils. Verify single origin for purity of Olive & Avocado. Use unrefined virgin cold pressed Coconut Oil. The best Fats are Animal Fats. Trustworthy & Healthy.

🇪🇺🇷🇺🇨🇳 Ex-Chair of NATO Committee is afraid that China'll block green energy materials for EU the same way as Putin blocked oil & gas supplies: "In 2022, Putin turned off our supply. I'm making a prediction! The same thing will happen when we switch to green energy. 90% of the raw materials for green energy (rare earth elements) are produced in China, and 60% are owned by China. If China blocks them, we won't have light, we will not drive, we will not work, we will not have heating, nothing." — Admiral Rob Bauer OK, it's RUSSIA who deprived Europe of oil & gas, not Ursula... (I guess he means the Nord Stream pipeline explosions in 2022 ... sure it was Russia...)

THE NIGHTMARE SCENARIO NOBODY IS TALKING ABOUT AN OIL + DOLLAR SHORTAGE The nightmare scenario nobody is talking about right now is what happens if the Dollar skyrockets at the same time as oil. Since the world's oil supply is purchased in Dollars, they are typically inversely correlated. A lower Dollar = increased international demand for oil. The only time we've seen a brief period of oil 🔼 Dollar 🔼 was in 2022, during the economic slowdown. The nightmare scenario we're facing is a global oil supply shortage at the same time as an economic crisis. Both of these compound the demand for Dollars because not only are nations forced to liquidate greater assets to purchase oil, but servicing sovereign debt becomes much more expensive because it's denominated in Dollars. This energy crisis could very well be the beginning of Brent Johnson's Santiago Capital Dollar Milkshake Theory and the United States' plan to take a large portion of its debt out of circulation.
