what are you doing man!!! ... the pipette is touching with the test-tubes and then you guys are using it to pipette out water again.. this is simply hopeless work... the distilled water is contaminated. Obviously, this will have no effect in this particular reaction but for chemistry practical, this is simply forbidden. Disliking the video.
