Watch A Glass Of Water Make These Arrows Change Direction
Refraction is just the best.
Here’s a quick optical illusion you can create to impress your friends.
1.Draw an arrow or two on a piece of paper and place it behind an empty glass.
2.Then pour in some water...
And watch the magic unfold.
The illusion is caused by refraction, with the arrows appearing to change direction.

When light goes from one material to another it refracts, or bends.
Light travels through the air, through the glass, through the water, through the back of the glass, and then back through the air, before reaching the arrow.
Wonderful.
pa Like if u like. Thanks folks!
