Have you ever wondered why it took you so long to try making ice cream in a bag? This fun and easy experiment is a great way to engage students and teach them scientific principles. The setup is quick and simple, requiring only a few ingredients that you likely already have on hand. If you don’t have rock salt (ice cream salt), you may need to pick some up before getting started.
To make the Ice Cream in a Bag Experiment even more engaging for your students, be sure to grab the free worksheet available by clicking the button below.
What can conducting the Ice Cream in a Bag Experiment teach your students? This hands-on activity covers a range of scientific fundamentals, including the different stages of matter, changes in phases, the impact of temperature on solubility, and the transfer of heat.
If you prefer a visual guide, there is a helpful video available that provides step-by-step instructions for conducting the Ice Cream in a Bag Experiment.
To get started with the experiment, gather the following materials:
– ½ cup half-and-half
– ¼ teaspoon vanilla
– 1 tablespoon sugar
– 1 gallon-sized plastic zip-top bag
– 1 quart-sized plastic zip-top bag
– â…“ cup rock salt (ice cream salt)
– 3 cups crushed ice
Follow these steps to make your own ice cream in a bag:
1. Pour half-and-half into the smaller zip-top bag and add vanilla and sugar. Seal the bag tightly.
2. Add rock salt and ice to the larger zip-top bag.
3. Place the smaller bag inside the larger bag and seal it tightly.
4. Shake and squeeze the bag until the ice cream thickens, which may take 5 to 10 minutes.
5. Remove the smaller bag and enjoy your homemade ice cream!
This set of directions yields enough ice cream for a small group of students to enjoy a spoonful each. If you need to make more for a larger class, simply triple the recipe or make multiple batches during your small-group time.

The art of glass blowing has been practiced for centuries, dating back to ancient Egypt and Rome. This delicate and intricate craft involves heating glass to a molten state and shaping it into a variety of forms using tools and techniques that have been passed down through generations.
Glass blowing requires a high level of skill and precision, as the glass must be manipulated quickly before it cools and hardens. The process begins with gathering molten glass on the end of a hollow metal rod, known as a blowpipe. The glass blower then blows air into the pipe, creating a bubble that can be shaped and molded into a variety of forms.
One of the most iconic forms of glass blowing is the creation of glass vessels, such as vases, bowls, and ornaments. These pieces are often made using a technique called free blowing, where the glass blower shapes the molten glass by hand, using tools such as wooden blocks and metal shears to create intricate patterns and designs.
Another popular technique is known as lampworking, where the glass is melted using a small torch and shaped using specialized tools. This method is often used to create small, intricate pieces such as beads and figurines.
Glass blowing has evolved over the years to incorporate modern technology, such as electric furnaces and computer-controlled kilns, which have made the process more efficient and precise. However, many glass blowers still prefer to use traditional methods, as they believe it gives their work a unique and authentic quality.
In recent years, glass blowing has experienced a resurgence in popularity, with many artists and craftsmen embracing the craft as a form of creative expression. Glass blowing workshops and studios can be found around the world, offering classes and demonstrations for those interested in learning the art form.
The art of glass blowing is a true testament to the creativity and skill of the artisans who practice it. From delicate vases to intricate beads, each piece is a unique work of art that showcases the beauty and versatility of glass as a medium. Whether you’re a seasoned collector or just starting to explore the world of glass blowing, there’s no denying the timeless appeal of this ancient craft.
