[…] This classic baking soda and vinegar experiment becomes extra magical when poured into heart-shaped molds. Plus the mixing of the baking soda and water adds a cool and welcomed sensory element (with a bit of a mess, but learning is messy!). We tried this activity from Sugar, Spice, and Glitter and loved it! […]

I see you don’t monetize your blog, don’t waste your traffic, you can earn additional bucks every month because you’ve got high quality content.

That’s a great question – if you had to use a metal pan, I would use something to line it so that you can easily remove the frozen baking soda cubes. Maybe an ice cube tray would be better – or lining the metal baking tray with parchment paper?
