Picture of Calculating the speed of light through hand sanitizer!
In this project, we will use Snell's Law to our advantage in order to calculate the index of refraction, and thereby the speed of light of through a hand sanitizer medium.

Step 1: Setup

Picture of Setup
Set up the optics kit with ray table/bench, laser/light source, and plan-convex tray. If you are not using a kit, you may make do with a protractor. Fill the tray with some of the solution.

Sorry, i did not understand calculations. Could anyone explain that?

All of a sudden there are a lot of Instructables on Optics. I'm going to dust off my "Jenkins and White".
Nice work.
If I remember correctly, the index of refraction equals the tangent of Brewsters angle.
