Fake snow takes about twenty minutes and buys you a whole afternoon of indoor play. This walkthrough follows Maqaroon, who lined up the most popular homemade snow recipes going around online and made all of them on the same board so you can see how they differ side by side.
Three recipes are worth your time, and all of them use things already in the kitchen or the bathroom cupboard: frozen shaving foam on its own, baking soda with cornstarch, and baking soda with shaving foam. The baking soda and foam version won - bright white, cold in the palm, and it packs into a snowball that holds.
What you need
- Baking soda, more than you expect. Buy the large box.
- Shaving foam, fragrance-free if the shop stocks it
- Cornstarch, for the shelf-stable recipe
- Water, easiest to control from a spray bottle
- Tubs with lids and high sides, plus a snowball mold
How to make snow at home: the best homemade snow recipe
The homemade snow most people are after is the baking soda and shaving foam mix. Pour baking soda a few inches deep, spray foam back and forth across the top, then push your fingers down through it and fold until no dry powder is left in the corners. It comes out bright white and cold in your hand, because the foam is evaporating against your skin. A shoebox-sized tub takes most of a one-pound box of baking soda and half a can of foam.
Instant snow is a different thing
Instant snow, the kind sold in sachets that erupts when you pour water on it, is sodium polyacrylate - the absorbent polymer used in disposable diapers. You cannot mix it from kitchen ingredients. A teaspoon drinks about a cup of water and swells into cold wet flakes in seconds. It is wetter and slushier than the recipes here.
Powder snow, foam snow, or crumbly ice
Each recipe lands on a different texture, so pick the one that matches what you are picturing.
- Frozen shaving foam gives crumbly ice crystals. The only genuinely cold one, and the only one that melts.
- Baking soda and cornstarch gives dry powdered snow. Sandy to the touch, and the color leans cream.
- Baking soda and shaving foam gives fine powder snow, bright white, and it packs clean. This is the fake snow foam recipe worth making if you only make one.
Fake snow for dioramas, villages and photo backdrops
For a diorama or a model village, use the cornstarch mix dry, with no water at all - it stays put, it will not wet cardboard or lift paint, and it dusts onto roofs and branches through a tea strainer. A window display or a photo backdrop wants the baking soda and foam mix, the whitest under a light. For a sensory tray, frozen foam is the one children remember, because it is cold to hold. If you want a winter scene sealed and permanent, a snow globe is the better route - none of these recipes survive being put in water.
Troubleshooting and how long it lasts
It went slimy. Too much water in the cornstarch batch turns it into oobleck. Add more of both powders until it goes crumbly again, and mist the water in next time.
It went powdery after a few days. The foam has evaporated out. Spray more in and remix by hand. If it will not hold a snowball, it is too dry.
How long it keeps. The two powder recipes last weeks in a sealed tub. Frozen foam is gone inside an hour once it leaves the freezer.
Mess and safety. Nothing here stains, but baking soda and cornstarch leave white dust on dark carpet and dark clothes, so work on a tray. None of it is food, so supervise toddlers and keep it away from a dog that licks everything.
Want more of the same for a rainy afternoon? There is slime, playdough, and kinetic sand, all of which keep better than snow does.
