No, a lettuce spinner is a little basket inside of a container with a handle that you can spin to turn the basket. You wash your lettuce and put it into the basket and turn the handle. The centrifugal force (I think) causes the water clinging to the outside of the lettuce to drain into the container.

I think if you filled the container and basket partially up with ice or crushed ice) and some water, it’d achieve the same result as the machine someone linked above
