To make a juice slushie in ten minutes you need: ice, salt, one small zip-lock sandwich bag, one big zip-lock sandwich bag, orange juice and a glass. The first thing you’re going to do is pour orange juice into the smaller zip-lock bag and close it.
Make sure there is no extra air inside the bag. Place that bag into the bigger zip-lock bag, then fill the rest of the big bag up with ice. Before you close the bag, pour salt over the ice inside the bag.
This will help the ice to get colder. After pouring the salt into the bag, close it. You may want to use gloves for the next part, as you’re going to pick the bag up and shake it for about five minutes. If gloves are not available, you can also wrap the bag in a towel or cloth of some kind while you shake it, to keep your hands from getting too cold.
After five minutes of shaking the bag, the orange juice will have turned to a slushie texture and is no longer liquid. If it is still liquidy, you may want to continue to shake the bag for a few more minutes until the contents reach the desired texture.
At this point, take the bag of orange juice out, wiping away the salt. Then open the bag up and scoop out the slushie mixture into a glass or a bowl. Now you’re ready to enjoy your slushie!
