So today me and my little sibling were having a discussion about how to keep ice cold in an average room tempurature control environment. Sibling : you put it in a cardboard box and put styrofoam around it and seal it off.
Me: take the cube, put a single layer of aliminum foil completely around it while standing in the coldest areas of the house, then take a thin copper tube and shape it to where it stays sturdy but not to tight around the cube. Put extremely cold water into the tube and seal it off. Then take a medium sized, average speed desktop computer processor fan and point it directly above the cube. And turn it on, obviously. Whos right (in your opinion) 1 for sibling, 2 for me. Just post the number and why below. (btw, i have years of experiance adding extra sources of cooling to computers, my sibling has the knowledge of a single expirement that she did in elementary school)
