Ice Cream in a Bag

INGREDIENTS

2 

small Ziploc bags

1 

large Ziploc bag

1/2 

cup milk

1 

tbsp sugar

1/2 

tsp vanilla

4 

cups crushed or cubed ice

6 

tbsp salt

DIRECTIONS

• Take a small sized sealable (zip-loc type) bag and add 1/2 cup of milk, and 1 tbsp of sugar. For added flavor, use 1/2 tsp of vanilla. Seal it up, getting rid of as much air as you can. Now double bag it inside a similar-sized bag.
• Throw 4 cups of crushed or cubed ice with 6 tbsp of salt in a large freezer bag. You can use any kind of salt, as you won't actually be eating it. The salt is there to lower the freezing point of water, if you want to get technical. Put in your little double bag, and seal the large bag around it, getting rid of as much air as possible.
• Now for the fun part—get shaking baby! Wrap the bag in a tea towel, or use gloves if you aren't feeling hardcore, but otherwise just shake the bag for at least five minutes before checking on its progress.
• You’ll start to notice it getting thicker by simply feeling through the bag. In eight minutes max, you should have some seriously delicious ice-cream; it will take longer if you are mixing a large batch.
• When you remove the smaller bag, wipe it down carefully to get rid of all the salt on the outside.
