This is an example of light reflecting off metallic matter: in this case, ornaments found on Christmas trees everywhere.
These are the materials Cher, Ali, and Kelly used to make the bubble mix. Among the materials are soap, glycerin, water, a cup, and a graduated cylinder.
This is a closeup of water, glycerin, and soap. (1/3 of the total mixture is each separate material) If you look closely, you will notice that the soap is floating on the glycerin and water. This is because the soap is less dense than the other two materials.
The brand of soap was opted to use was Dawn soap
This was the glycerin we used. You will notice on the label that this is CERTIFIED glycerin, nmeaning it is acceptable for scientific experiments such as ours.>
The mixing process... we are using a stirring rod to mix the water, glycerin, and Dawn soap together so it will effectively form bubbles.
The mixture after stirring. Isn't it beautiful?
This is our bubble wand. We made it ourselves! All you need is a piece of wire and the ability to make a small loop.
This is a sodium light we used to emphasize the reflection of light off of bubbles with a colored light. This particular light is yellow.
One example of light reflecting off of the bubbles. The pattern formed on this bubble somewhat resembles a tiger's stripes.
Cher is holding two extremely flat glass disks. Placed one on top of the other, the air between produces the same effect as a soap bubble when held at the proper illumination.
Double bubble!! How fun is that? This was caused by blowing a bubble and it doesn't pop but divides into two.
Cher demontrates the art of blowing bubbles.
Kelly holds the bubble-bearing filmholder underneath the sodium light.
We are using a filmholder in the place of a bubble-wand to hold bubbles at its rim. This is a closeup of a bubble in the filmholder
Kelly's reflection in the bubble
The fluorescent overhead lights are reflected in one of the bubbles.
Kelly attempts to catch a bubble in our homemade bubble wand.
This is a chart illustrating constructive and destructive interference, the effect that causes the different colors (click to enlarge).
