In this funny video, science teacher and YouTuber Jacob Strickling invents a funny hack after his students fail to interact with him during his online Zoom lessons.

Jacob prints out a yellow thumbs up and sticks it to the end of wooden dowel with some duct tape. A rivet drilled into a motorised wheel is then poked through the end of the dowel.

Now Jacob is able to give himself a thumbs up with his motorised contraption. Brilliant!

The clip was recorded in Jacob's New South Wales home on Tuesday (April 7).
