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
Do you ever have to note or recall information afterwards? Because for me it wouldn’t be the sitting in a call for 5 hours part that would be the problem, it would be someone asking me to tell them anything that happened in it that would be the problem. I couldn’t even tell you who was in it
