#iTeachphysics Noticed 2 sets of reflection in my reading glasses of the 4 candelabra lights above my kitchen table. One set is of the 4 white bulbs I expect. The other reflection makes the bulbs blue. Another pair of glasses makes the 2nd reflection green. Any thoughts on what is going on?

Reading glasses held in my hand, showing 2 sets of reflections of the 4 lightbulbs above my dining room table. The pendant style small chandelier has 4 white candelabra shaped bulbs. In the reflected image we see a set of 4 white bulbs and a second set of 4 green bulbs. What do you think is going on?A different pair of Reading glasses held in my hand, showing 2 sets of reflections of the 4 lightbulbs above my dining room table.

#iTeachPhysics 20 experiments in 60 seconds. This started with a joke about using textbooks in lab. I went through my files and all 20 use textbooks. How many do you recognize? How many are new to you? Maybe I just want BlueSky to be the new physics teaching place. Post your textbook pictures...
