Instant Snow = Instant Joy!
This Insta-Snow Powder is a huge hit with my kids! Just add water and it instantly fluffs up into cool, realistic snow — no mess, no mixing, and no waiting. We’ve used it for sensory bins, holiday play, and homeschool science. It’s soft, fun to touch, and lasts for days if stored right. Great value, this bag has lasted a few years since you only need a little bit for a lot of snow! A great winter activity any time of year!

Easy activity set ups for children.
My kids, nieces, and nephews are in love with this. You just need a tub and a little goes a long way with these. I alway pull these out for family gatherings to distract the kids. Just don't pour too much water or else it'll be mush. I usually just eye ball the water and powder. Only suggestion is to do it outside or have a tarp on the floor because sweeping these off the floor is tedious. If you don't mind that then it's all good. I usually just throw some small toys, cups, and spoons in the tub with the snow powder and the kids just play all day. It doesn't melt/clump and stays pretty good for 3 days in a tub. It may last longer but I usually just toss it away after 3 days. Will be purchasing again.

The students LOVE this!
The students LOVE to play with this stuff! (And so do any adults that happen to walk into my classroom). It does feel so much like snow. I have no idea how, but it even feels cold, though not too cold to play with. The students’ favorite part is watching the powder swell up as the water is added. It goes through quite a change! I usually have to add more water each day and either add more insta snow powder every couple of days. A little goes a long way, so the bag will last for at least a couple of weeks in a classroom.

Feels just like snow
I was very surprised at how quick this turns into “snow”. It was a great little experiment to do with the kids indoors.

Great for immediate play. Does not reuse well as advertised
I bought this for our small red helpers of Santa to play with. It was absolutely perfect for that task. We had several days of fun, as the snow dries out you add a bit more water and mix and viola it’s great again. The kids absolutely loved it. Once we were done, I sectioned it out into small bits and spread it very thinly to allow it to dry back into a powder. We stored it the house in a bag fully dried in powder form. It was powder last year but we did not end up using it for shenanigans. I glanced at the bag at the beginning of the season this year and it appeared to be powdery but when I removed it to reactivate it as advertised, it had become one solid block and when water is applied it became a gooey gel that dried my hands out very badly and had a not so great chemical ish smell to it. I immediately threw it out. Anywho, I have detracted one star for the reason that the bag and website say as long as it’s fully dried it’s pretty much reusable but despite having been extremely careful and having stored and dried it back to a powder, that was not the case for us. That aside, it’s a really fantastic product and we got a ton of fun from it

Fun Winter Themed Steam Activity
My students love this! I add polar animals to a couple of tubs of “ snow “ and it is the favorite play station in my classroom.

This feels like magic!
We could not believe how easy and fun this product is! It truly feels and acts like snow! It felt like magic to have snow in the middle of the summer.

Small bag but good product
It’s a small bag but it has a lot of product. I’m using these for slime so I’ll probably purchase a bigger amount next time.

Muy divertido
Rinde mucho. Yo solo use 10gr y obtuve una cantidad considerable ademas la textura es ligera y fría. Trae un cuchara mediadora e instructivo lo cual aprecio porque con otras marcas es a prueba y error para obtener la textura deseada.

Divertido y Real
Si se hace nieve, y se siente fria y rinde mucho vale la pena solo cuando quieres hacer bolitas de nieve no se pega tanto entre ella asi que terminas aventando puños en lugar de bolitas pero se divierte bastante
