Saw this on YouTube today. Interesting & expandable too, with the right creativity. I suppose a person could 'supersize' it by using larger buckets or drums perhaps & an old furnace blower. Although you may have to take into consideration the effects of the volume of air moving & cubic area inside the containers when up-scaling it. Worth a look anyway, thought I'd share.
