Montreal dad completes an experiment with shadows during the lockdown.

The clip, filmed over three days shows David Freiheit filming the shadows of a street lamp satisfyingly matching up with the chalk outlines him and his kids drew.

David told Newsflare: "I outlined the shadows of a lamp post at varying stages of the morning and waited until the next day to do a time-lapse. The first day clouds came in. The second day it rained, and I had to redo the chalk lines. The third time it worked perfectly."
