{Summer} Science: Ice Cream in a Bag

Today was the first day of hell Summer Vacation.

It did not go well.

Using the system they use in her fourth-grade classroom, Little was placed on varying shades of the behavior rainbow until she landed on:  RED  

We took a deep breath, hit the do-over button, and decided to break up the day with a little science.  Namely, ice cream in a bag.

Ingredients/Per Person:

  • Ice
  • 1 C Half-and-Half
  • 1/2 C Salt (coarser the better)
  • 2 T Sugar
  • 1/2 tsp Vanilla Extract
  • 1 Pint-Size Ziplock Bag
  • 1 Gallon-Size Ziplock Bag
  • Mix-Ins (optional)



  1. Combine sugar, half-and-half, and vanilla in the pint-sized bag and seal tightly.
  2. Place salt and ice in the gallon-sized bag, then place the sealed smaller bag inside as well.  Seal the larger bag.  Now, shake the bags until the mixture hardens (about five minutes).
  3. Remove the smaller bag.  Add any mix-ins and eat the ice cream right out of the bag.
  4. Enjoy your kid’s amazed expression.
