Ice Cream in a Bag Experiment

Ice Cream is a quintessential function of summer! Just it also makes for a bang-up (and delicious) science experiment… No fancy machine or cranking required!

This 'recipe' was adapted from Steve Spangler Science.

How To Make Ice Cream In A Purse

Homemade Ice Cream In A Bag Ingredients:

• 1/2 cup half-&-half (or milk)
• 1 tablespoon sugar
• one/ii teaspoon vanilla ice
• ane/two loving cup of stone salt

You lot volition too demand:  2 sandwich-sized baggies, 2 gallon-sized baggies, and winter gloves.

*You lot can impress off the ice cream in a bag recipe with step-by-footstep instructions by downloading your own free copy of our Fascinating Science for Kids ebook.

Ice Foam In A Bag Experiment with Footstep by Step Instructions:

 1. Pour 1/2 cup of half-&-half or milk into one of your sandwich-sized baggies. We used milk and information technology worked wonderfully. Add one tablespoon sugar and 1/2 teaspoon of vanilla extract. Get all of the air out and then seal the bag. Place your filled bag into another sandwich-sized baggie and seal.

 2. Put your double-pocketbook within of a gallon-sized baggie and add your ice and 1/two cup of rock common salt. Place this bag within another gallon-sized bag (you will have two pocket-size bags and 1 big purse inside).

 iii. Take your child put on some winter gloves and start shaking!

 Milkshake the purse for about xv-20 minutes, passing it around the various members of the family unit!

 I put a dishcloth around the bag when it was Niggling Blood brother's turn…he karate-chopped it more annihilation, just it turned out merely fine!

 All done! Nice and soft, but even so slightly solid!

 Set up to be served! This simply makes a serving of water ice cream. If you desire to double the recipe, you can (simply utilize quart-sized baggies instead of sandwich-sized). Don't effort to do any more doubling, though, or information technology will exist likewise heavy for the child to conduct when you add together ice and stone salt.

Little Brother canonical!

Definitely Big Brother approved! He was SUPER excited most how yummy "his" ice cream turned out!

The Scientific discipline Of Water ice Cream In A Bag:

The common salt lowers the temperature at which ice freezes, or raises the temperature at which information technology melts (which is why we use it on the roads in the winter). Instead of melting at 32 degree Fahrenheit (0 degrees Celsius), the rock salt causes the ice to melt at a temperature much lower, depending on how much salt you add. The more rock salt yous use, the lower the temperature the ice will cook at. This creates an environment that the water ice cream mixture can freeze below the normal 32 degrees. Then the salt/ice slush absorbs the rut from the cream mixture, lowering the temp of the cream and causing the foam to 'ice', creating the yummy ice cream texture!
