I made ScienceFix.com to share my favorite demos that I do in my middle school science classes.

Video Demo: Fish Tank Spectrum

When studying light, students need to learn that visible light can be refracted into its different wavelengths.  Of course it's ROYGBIV (red, orange, yellow, green, blue, indigo, and violet).  A simple prism is usually used to do this, but I think there is a better way.  Fill up a fish tank with water, put it in the sun, use a mirror and ta da a spectrum!  Check out the video.

    In my studying time I learned this art of great science because our teachers also give us the same lecture that you shared in your video. The fish tank passed the different light that we use to transfer from our hands.
