Make Ice Cream in Ten Minutes
Did you know that in 1984, former President Ronald Reagan designated July as National Ice Cream Month and the third Sunday of July is the National Ice Cream Day. This Sunday, July 15th is National Ice Cream Day.
Just in time when all across the nation, people are sweating their fannies off. It think what we’re going to do is take a little tour of Cocoa Beach and see if we can find an ice cream parlor, just to check it out.
We’re going to take a little tour of Scoops, our local ice cream shop in Cocoa Beach. We’re going to find out what the most best selling ice cream inside of this store.
What’s your best selling ice cream?
Our best selling ice cream is the “Garbage Can”, it is a vanilla-based ice cream. It has 8 different candy bars in it. It sells very fast.
Mmmm, this is delicious!

Now let’s say in the middle of the night, you get a craving for ice cream. All the ice cream parlors are closed. You don’t want to go out to the store but you do have ice, salt, vanilla, milk and sugar and Ziploc bags and you can make your own ice cream in 10 minutes or less. And you don’t need your goggles on this one.
What we’re going to do right now, is we’re going to show you how to make your own ice cream at home.
We’re going to take an empty quart-sized zip lock bag. We will place a half-cup milk inside of the bag. Next we place a half-teaspoon of vanilla into the bag and the last ingredient we will add will be a one tbsp of sugar into the bag. So we’ve used a half-cup milk, half tsp of vanilla and one tbsp of sugar.
We’re going to try to remove as much air as possible and seal the bag. This bag will be placed inside an empty quart-sized zip lock bag and sealed to prevent leakage.
These two bags will be placed into an empty gallon-sized Ziploc bag. Our next step is to place 4 to 6 cups of ice surrounding the quart-sized ziploc bags.
Our next step is to add 6 to 8 tbsps of table salt, pour it over the ice surrounding the quart-sized Ziploc bag. when we add the table salt, we are lowering the freezing point of the ice. The is an example of an endothermic reaction. We’re going to shake the bag for about 10 minutes. It’s going to get mighty cold, so I’m going to put my gloves on.
If you have ever lived up north, you have probably seen the highway department spreading salt on the road to melt the ice. we can demonstrate the effect of this on salt lowering the freezing point on a smaller scale, by placing the salt on one piece of ice and compare the melting rates to an ice cube without salt.
I’ve been shaking this bag back and forth for 10 minutes now. Let’s see what kind of temperatures we have inside this bag. We have 22 degrees Fahrenheit and about -9 degrees Celsius.
What we’re going to do is we’re going to take out our quart-sized bag and get a little look at it. so we started off with a liquid, and we now have a solid.
We’re now ready to take the ice cream out of the Ziploc bag.
So on a hot, humid summer night, why not make your own ice cream and learn some science as well.
