How Much Does a Shadow Weigh?

I love Vsauce videos and this is no exception!

Woah...mind blown (twice). I mean, I knew that light was slower in air, but ~1M m/s slower? Crazy...

And the "speed of push" being the speed of sound? Love these types of videos...

Ya, I have known forever that sound traveled in water faster than air...but I didn't think of the larger implications of what this meant in reality. And just like light, there is a formula for calculating the speed of sound in objects, which by conscience is also the speed of change in the object, something I never placed in the same realm before (sound was related to motion in my mind, but in reality sound IS MOTION).
