Night light craft project

Our kid brought this night from his preschool one day. It took them two days (I believe) to make it. In the video I tried to catch the light changing the colors. It is glued to the bottom of the lid. The water itself is green. There is a nice shell, a toy shark and a piece of plastic weed together with the colorful stones in the jar. The jar itself is pretty too! When you see the rows of "bubbles", they are actually a part of the jar glass. Cool craft project for the 4 year old's!
