In the age of Instagram, instant rice and instant gratification, it can’t come as much of a surprise that there also exists insta-snow.
How does it work? Carolyn Leap knows. Our youth educator facilitates an Outreach Program here at HMNS called Science on Stage, and my favorite topic has to be Cool Chemistry. I love watching her stick things in liquid nitrogen, set things on fire that never burn and make a cup of water disappear in an instant. Carolyn is magical.
Okay, she isn’t really magical. Everything she does is totally explainable with science, but seeing kids watch these demonstrations for the first time is super fun. They are totally amazed!
One of the topics she focuses on in a Cool Chemistry program is polymers. My favorite polymer demonstration has to be instant snow. If you’ve never seen it done, it is super fun! But what is it? And more importantly, where can you get some? First things first, my friends…
“Whether it’s called ‘Amazing Snow Powder®,’ ‘Insta-Snow®,’ ‘SnoWOW®,’ ‘Magic Snow®’ or anything else, any faux snow that grows when you add water works the same way. Instant snow powder is made of some very large molecules (polymers) composed of repeating units that are hydrophilic, or ‘water-loving.’ Most synthetic polymers are not hydrophilic; plastic soda bottles, PTFE (Teflon®) coatings, and PVC pipe, for example, are not.”
“As you add water, the powder acts like a bunch of very tiny but very good sponges. When you look at a regular kitchen sponge, you can see the pores that the water fills in; with instant snow powder, the places the water occupies are way too tiny to see, but they’re still there. Fake snow’s chemical name is ‘sodium polyacrylate,’ but the absorbent polymer in disposable diapers goes by the same name, because they have very similar chemical structure. Most people call instant snow by its simple name for clarity. Depending on who you ask, polymer ‘snow’ was first developed either as a blood absorber for hospitals or as a material to use in indoor snowboard parks in Japan. However it was invented, it’s awesome!”
Want some insta-snow of your own? Visit the HMNS Online Store and pick some up for yourself! These little jars make perfect stocking stuffers, particularly for kids from southern Texas who may have never seen snow before. Want to keep it after the holidays? You can dry it out and store it for the next year, but it takes weeks to months in the Texas humidity. We tried it one year and finally gave up around spring break!
