This strikes me as an example of innovation delivering real practical value by saving limited personal labor time. It takes time to pull out the vac/put it away, or go to the car wash to vacuum out your car. Especially useful for an active family. HondaVac
Cherrios be gone!
Recently scientists successfully documented the use of tools by crocodiles. They are able to use sticks they arrange on their heads to attract birds to land. This often ends badly for the bird. They even appear to show a bias of use during spring matting seasons when there is a high level of activity.
Previously we assumed that only higher level primates and certain birds where capable of making and using tools. Had we been asked if crocodiles use tools, many likely would have scoffed at the idea.
Project assumptions must be examined with a critical eye.
