A water puddle in the middle of a sidewalk??? Look carefully this is just a chalk drawing...
Puddle Chalk Drawing
This is an awesome chalk drawing done on the road. It gives a 3D effect when seen at a specific angle.
Stare in the center of this picture and the two rings would appear to be expanding! Also, move your head back and forth while staring at this picture, the two rings would spin in opposite directions!
This is a great chalk drawing. When you look at these special drawings from a certain angle, they appear to stand out.
