thats what i did. if you press the spray enough times you can pump the cold water to the ic. I tried it and put my hand in the scoop to feel the spray and it is colder. Not too sure how much it helps but oh well, I had fun.Hmmm, I put ice in mine on nights I'm out "playing around". I believe it does make a differance. When spraying the I/C with ice water it does stay very cold to the touch. When I don't use ice the I/C just feels wet.
