I saw that video the other day and it's great.  I highly recommend the Vsauce channel.  Very cool videos.

He talked a little fast for me to grasp everything, but apparently a shadow weighs less than the light surrounding it.   8)

Going off my (sort of) good memory the video was more about how much less an object weighs when not in light versus in light.  I guess doing some math the city of Chicago weighs about 400lbs more on a sunny day.

He also did some discussion on faster than light travel not being possible and the speed of light being different through different mediums.

Kids aren't paying attention most of the time in science classes so it seems silly to get worked up over ID being taught in schools.
