Things aren't always as they appear - light refraction experiment
Ever reached down into the bath tub water to grab a toy and found that it was not in the position it appeared to be in? What you are experiencing is the effect called refraction. When light enters the water (or any transparent material) it slows down slightly. If the light enters the water at an angle then this change in speed causes the light beam to bend away from its original path. This is called refraction.
