dude, dont try the bong. you want some super cold hits huh? alright, take your slider out of your bong, no need to break it. take bong, and put water in it. next take maybe a teaspoon or two of salt, and throw it down the downstem so it gets in the water, stir. place bong in freezer.

if its too big, put it in a cooler with salty ice.

after a while the water will be super cold, colder than freezing, but not ice. pack the bowl, put the slider in, and boom. super cold hits, though like was said before, the thc and tar can condense back, so you will get a lot of resin build up, and probably get less high as a net value for your weed, but huge smooth hits ensue.
