Gatorade, you drink it all the time. But have you nerds ever wondered what its index of refraction is? Well, with this amazing experiment, you will be able to find out! So fasten your seatbelts, and lets get going!

Step 1: Gather Your Materials

Things you will need:
• Gatorade
• Water, this will serve as the standard
• Light source
• Container for Gatorade, preferably a clear semicircular one
• Protractor
• Track to stabilize materials
• Slit plate and mask, this will focus the light to make it easier to see the angles

Step 2: Setting Up the Experiment

To start out, place the track on a smooth level surface. This will ensure that the Gatorade stays stable in the container and that the light goes through the container completely. Place the light source on one end of the track so that it faces the opposite end. Afterwards, place the slit mask and the plate together about 10cm away from the light source. This will focus the light into a line so that you can see where it hits the Gatorade and how it refracts. Put the protractor about 20 cm away from the light source and place the container on top of it. If you have a semicircular container, you should point the round side towards the light source to make it easier to read the angle at which the light refracts.

After you are done, you should have something similar to the picture above.
Nice job- some confusion about critical angle - but definitely more fun than your usual lab! :)
