Reversing Arrow
Science
Did you know you can change the direction of an arrow, just by using water?
You?re not gonna believe your eyes. Look at this vase. It?s filled full of water. On the other side, I have an arrow. Pay close attention to the arrow. Did you see that? The arrow switches direction. The science? It?s simple. It all about light refracting or bending through the glass vase, the water, and the air behind the vase. It makes it look as if the arrows switches directions.
