Let's make snow globes--or do a couple of fun experiments! Two chemicals you'll need are benzoic acid, ammonium chloride, and instant snow. MEL Science has this experiment, Snowfall in a Bottle, which requires 70 grams ammonium chloride. Just halve the amount of water if you order 30 grams instead. Flinn Science's Blizzard in a Bottle requires just one gram of benzoic acid to use in baby food jar snow globe. Home Science Tools has a DIY Snow Globe project. A beautiful mess has a snow globe greeting card craft. What about the instant snow? MEL Chemistry has this experiment with instant snow and methylene blue--also available at HST. If you haven't used instant snow before use Steve Spangler's instructions. Science Sparks has these fun ideas to do with instant snow. Instant Snow is also sold as sodium polyacrylate. Paul and my husband, Rob, loathe crafts. We’re playing with the Instant Snow and I ordered benzoic acid for next week. Below are pix with instant snow, or sodium polyacrylate. I tried phenol red, an indicator, with the snow. There was a color change in the beaker, probably from residue in the beaker. The phenol red did dye the snow.
