Just when you think there’s nothing new to say about blenders, enter Blendtec. Actually, enter the Blendtec videosWill it Blend?. Call it a publicity stunt, but it’s a good one. Blendtec, which sells commercial-grade blenders akin to those you see in coffee shops, has entered the home-blender arena with their Total Blender and a series of short videos showing a lab-coated, safety-glasses wearing man blending outrageous things. He blends an iPhone, a video camera, glow-sticks, an iPod, golf balls, marbles and on and on and on. Call us gullible, but this blender reduces everything from cubic zirconia, a stuffed toy, a stun gun, a Rubik’s cube, a DVD and a hearing aid to tiny bits and pieces. Warnings of “Don’t do this at home” pepper the Web site. Of course there are plenty of videos and information about blending edibles such as smoothies, bread dough, peanut butter, hot soup, salsa, ice cream, etc. The blender is good-looking, with a digital display and lots of functions. It’s heavy and solid. The Total Blender isn’t cheap at $400, but will draw ooohs and ahhs from your party guests, even if you’re just blending a margarita, not a cell phone.
