Spitting in someone ' s face is much faster and easier to coordinate . <| sep |> screenshot and see if you can get them to price match it if its higher on monday personnal reccomendation <| sep |> who the fuck is barbra dunkleman and why the fuck should we care ? <| sep |> Bet it cost you like 50 dollars or how ever much that is in Japan . <| sep |> You might actually see the opposite because the vacuum cleaner ' s fan blades are designed to push air at a particular velocity . When no air is moving , the blades of the fan are the least efficient and will have peak drag , which will translate into the highest motor load and the greatest power draw . Think of it like a car . does your car ' s engine generate more energyuse more gas when you ' re accelerating or when you ' re cruising on the highway ? How about when you try to accelerate with a big trailer behind you extra load ? Cruising for a propeller means normal airflow through it . Not saying you ' re wrong here , I would have to go put the KillAWatt on the vacuum and give it a try . I just don ' t think that it necessarily uses less energy just because its input is blocked . I think that may actually make it work harder .
