Blender

I found this definition :
blend·er  (blndr)

n.

One that blends, especially an electrical appliance with whirling blades for chopping, mixing, or liquefying foods.
It seems some people didn't read the definition until the last word : "FOODS" it says !
Well, I must thank one of my students for sending me this link to a crazy website you can visit just by clicking on the name "Will it blend ?"
Now, I couldn't resist to the fun, and I checked YouTube to find out weather those crazy vids were also available, and they are, all of them!
I selected the most appropriated for my students in IT. I like his humour about blending the ashtray users !
