Sometimes it’s easy to think our electronic devices have minds of their own. No doubt we’ve all wanted to yell at our computers at some point for behaving badly, and some of us probably have. But has it ever yelled back?

It’s not as far fetched as it may sound. Kelly Dobson of MIT’s Media Lab created a blender that is interactive, sensitive and “talks” back. Blendie, as it is affectionately known, is voice operated and changes speed with low and high pitched growling. Click the video above for an amusing demonstration.

Not only does this little machine blend engineering, psychology, and design - Blendie whips up a mean margarita!
