This is a lab challenge AP Physics 1 students completed at the end of a unit on one-dimensional motion and free fall. The goal was to have the egg hit a moving target (me!), moving at a constant speed. The students needed to calculate the amount of time the egg would take to fall to the height of the helmet and estimate the distance I would cover in that same time. Each group then placed a cup at that calculated distance away from a target right below their release point. As I walked past their measured cup, they would release the egg, so that I reached their target just as the egg reached my head height!

$Total Internal Reflection Demo #1 (Oil to Air) Total Internal Reflection (Demo #1) When light travels from a medium of higher index of refraction (oil) to a medium of lower index of refraction (air) the light bends farther away from the line perpendicular to the boundary between the two surfaces. If the angle of the light is greater than the critical angle for oil and air, then all the light will be totally internally reflected. None of the light will be refracted into the air. Total Internal Reflection (Demo #2): https://youtu.be/JLpdAQ0zPdQ I shot a laser into the side of a container filled with oil and water. The laser initially entered the oil layer. When the light hit the oil-air boundary, its angle of incidence was greater than the critical angle for vegetable oil and air (about 43 degrees), so all of the light is reflected back into the oil. No light is refracted out into the air. This is called total internal reflection. Total internal reflection happens again when the light hits the oil-water boundary. The angle of incidence is greater than the critical angle for vegetable oil and water, which is around 65 degrees.$
