be carefull with salt or you will quickly have frozen drinks. After making ice cream one day, I decided to teach the grandkids about how salt lowers the water temp. had them put their warm plastic water bottles in the remaining ice water all water, no ice left. It only took about 15 minutes to turn the bottle into completely frozen drinks. Course they were scratching their heads since the "ice" water was liquid, but the bottles were froze solid.
Neat science experiment for them.
Saturated salt water will be at 0F. That's the OF reference for the F scale, with 100F being human body temp. course they were off a little with body temp.
