Vegetable oil makes Pyrex glass disappear because both materials bend light in the same way, with a refractive index of 1.47.

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

Subscribing to my only fans makes my clothes disappear 😱

I kbow how it works but brain still reports this as magical and unexplainable

Miniature illustration of the process of extracting the crude oil..

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

Vegetable oil will make you disappear too. Use olive oil. 🇮🇹

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.

Happy Sunday everyone 🙏

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.
