While we all have read the theory of refraction in our physics classes and the optical illusion that water causes, rarely have we seen it come to effect. The video herein shows how a glass of water creates an illusion.
A placard with arrows pointing to a particular direction is placed on a table. Thereafter, an empty glass is placed in front of it. While the arrows get refracted from the glass, something exceptional happens when the glass is half filled with water. It is amazing to watch the optical illusion that the glass of water creates. While it may seem to be magic to normal people, those who are well-read will know that it is the refraction of light that causes objects to reverse. The glass of water acts as a magnifying glass expanding the size of the image considerably.
Watch the awesome scientific fact that would leave you dumbstruck. Know that it isnt any magic but simple refraction of light!
