Disappearing Glass
This Demonstration is included in a bundle of 101 Science Demonstrations & Experiments. You can find this bundle here in my TpT Store. These exciting demonstrations use mostly inexpensive materials that you can find around your home or can be easily purchased. I show how to run the demonstration, give helpful advice and explain the science concepts behind it. Many of these demonstrations can be turned into STEM projects for your students.

Materials needed:
2 Glass Containers (one that can fit inside of the other, without any writing on it)
Light Corn Syrup
Directions:
- Place the smaller glass container inside the larger one.
- Pour the corn syrup into the smaller container AND into the space between the two glass containers.
The Science Behind this Experiment:
How does this work? This demonstration has to do with refraction, or, light being bent. When I hold up the glass without corn syrup, you can clearly see both containers. This is because as the light is going through the glass and is hitting air and passing through glass again, the light is refracted. The light is refracted because glass and air have different indexes of refraction. Glass and corn syrup, however, have roughly the same index of refraction. As light passes through the glass and corn syrup, it does not bend, and the inside glass appears to disappear!
