Visual results of light bulbs lit by a direct current  versus light bulbs lit by an alternating current.  A direct current gives a continuous light  while a bulb lit with an alternating current is actually flashing on and off 120 times per second, not 60 seconds as stated in the video.   

Homemade science is a collection of  classroom tested ideas,  suggestions, projects, and experiments  that I have  used  in  teaching physical science for the Annville-Cleona school district in central Pennsylvania.  I am currently in my 40th year of teaching.   My intention is to share these ideas  with other teachers or anyone who has an interest in science.    I have found that designing and building my own equipment has taught me more  than any course that I have ever taken.  I hope that you consider trying this for yourself..  I also share  and show some of these ideas at workshops,  science conferences, or  inservice presentations.
