$Vegetable Oil and Pyrex have the same refractive indexes of 1.47. When light travels through the glass and then the oil, the speed of light slows down and on reflection, makes the glass seem invisible.$

I like videos because pictures make my curves disappear the same way yours disappear when you stand up. 😩

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.

uranium glass glows, It contains small amounts of uranium dioxide, which makes the glass fluoresce a bright green under ultraviolet (UV) light Wait for it

50 cal shot at a Tesla Cybertruck and didn’t penetrate through the glass. Armored Cyber Glass makes the most tough, thinnest and light bulletproof windows. #

‘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

$This When a beam of light passes through different glass shapes, its path changes because of refraction. Refraction happens when light moves from one medium to another—such as from air into glass—and its speed changes.🔦$

🗣️ "It makes complete sense." Can Thomas Tuchel find a way to fit both Morgan Rogers and Jude Bellingham in the same XI for England? 🤔

Japan has invented a beer glass that makes you drink slower. The shape of the glass slows down the pace of drinking by about three times.

I love how the animation is a combo of both rigs and hand drawn The way they have it designed makes both techniques blend together really well

A 'Kattar' Bengali Hindu • Saffron Flag outside the House. • Inside the House, Full Of Bottles Of Country Liquor. 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
