Well, we have some competition here - seems my cement mixer is nothing compared to what is available in a blender.

I googled for world's largest blender and VOILA! there exists one that will hold 500 GALLONS.

Check out the video to see it.

P.S. - I have ordered one for Thursday's Bar. Bring the neighbors.
