And you should end up with the white part of the spool, that will be used to support the LED's. The same thing happens after rain, when the water droplets that are left suspended in the atmosphere act as glass mirrors to refract the light of the sun. Here's what you'll need to follow along with the build. A diffraction grating is a set of many small prisms packed into a small space. Instructions: Fill the glass almost to the top with water. The circuit whit the 555 timer could be simpler. Triangular prism. 1. Make Your Own Rainbows. 3.0 out of 5 stars 20.
