Does it take a special type of blender to make smoothies?

Question

Or am I just doing it wrong? I have what I consider a typical blender that you might find in any American kitchen. It's a glass container with a cross shaped blade. The problem I have is that pieces often get underneath the blade and don't get blended at all. With smoothies in particular as well, if it's too thick the blade tends to spin too fast and keep everything pushed out to the sides and not actually blend. This is mostly a problem if trying to make a thick milkshake.

I have tried adding in thing like fruit while the blender is going in hopes that it wouldn't make it to the bottom without being blended but that doesn't seem to work really well. I've been reduced to blending multiple times (starting with a small amount of well blended material and slowly adding in the "chunks" from the previous attempt while the blender is running), but that is fairly time consuming.

Answer

Ahh, the complexities of blending. Have you tried pulsing the smoothie? Short bursts tend to stir up some of the stuff that sneaks below the blades.
