Make Gallons of Snow in Seconds:

The Original Instant Snow Polymer

As everyone knows, snow is a seasonal phenomenon. In some areas of the country, it doesn’t occur at all. Snow can’t be brought inside for study or playing with friends. So, when snow (and fun) is on the mind, let your your young scientists experience hours of entertainment with the Steve Spangler Science Insta-Snow Powder kits, delivering realistic and fluffy snow that can be dried out and reused countless times. This fake snow won’t feel fake at all. Just add water and watch in amazement. Within seconds, the mixture transforms into a solid and then erupts into a fluffy, white, snow-like material. The best part? There’s no stirring required. Watch as it instantly expands up to 100 times its original volume before your eyes. Our Instant Snow Powder kit is a true wonder and a versatile learning aid for the classroom or playtime.

Choose Fake Snow for Real Fun in the Classroom

Insta-Snow isn’t just a cool demonstration tool. Educators have found great uses for instant snow from early childhood sensory tables to advanced chemistry experiments. No matter what quantity of Insta-Snow you choose, you’ll get all of the materials you need in this comprehensive kit, including mixing instructions and an in-depth scientific explanation about polymers.

The Learning Opportunities of Playing With Snow

Oh, the wonder of polymers! Explore the fun side of learning using the ever-changing science of polymers. As students experiment with our Insta-Snow product, teachers and parents can discuss the application of polymers in everyday life. Kids will be excited to witness the magic of Insta-Snow as you explain to them how this substance changes from a liquid to a solid.

Sizes Available:

  • 3 gallons (100g)
  • 6 gallons (200g)
  • 12 gallons (400g)

Why Does Play Snow Still Feel Cold?

Since the snow is almost entirely made up of water, the water is bound to evaporate when exposed to warmth like your natural body heat. The process of evaporation produces a constant cooling effect, which is why Insta-Snow is so much fun for kids to touch.

How Long Can You Use Fake Snow?

The snow will start to dehydrate after a few days due to the process of evaporation. Luckily, there’s a simple solution. Just spray the top of the snow with water and fluff the snow with your fingers to give it a fresh, renewed look. You can also let the snow completely dry out to use it over and over again. The dry form of Insta-Snow powder will last forever.

How to Make Instant Snow Igloos

Here’s a recipe for fake snow creations at home. You can have fun building a snow fort, an inventive igloo or anything you can imagine by freezing blocks of Insta-Snow with an ice tray from your fridge.

      As a third-grade science teacher, I purchased this product to enhance my lessons, and it has been a hit with my students. It’s an excellent resource for teaching about weather and is highly engaging during its initial use. However, the only drawback is its limited longevity, it doesn’t last long and can develop mold fairly quickly. Despite this, it serves its purpose effectively for short-term educational demonstrations. Overall, a valuable teaching tool.
