Remember Your Childhood Kaleidoscope? This Is How It Was Made…
Perhaps you had a kaleidoscope as a kid -- or maybe you even still have one as an adult. As cool as they are to play with, have you ever stopped and researched how they actually work?
This video explores the history of the kaleidoscope and how it's made, and the process is pretty surprising. It makes sense that it would be slightly complicated, given what they actually do -- but we never thought that putting together a kaleidoscope would be as involved as this. Check out the video from Discovery Channel UK below.
