|
1. Turn on the laser aimed parallel to the front of the classroom. Hold the blocks so that class members can see the beam totally internally reflected from various walls of the lucite blocks. |
|
2. Aim the beam through the water tank at the stopper on the opposite side. Pull the plug and notice that the beam follows the water stream. The beam bends more as the stream does. Put your hand in the stream, or do other tricks to dazzle your audience. | ![]() ![]() |
