The idea was that where we sprinkled the salt, it would soak up the blue paint and leave an effect looking like snowflakes.
Aurora went a little overboard with the salt application, though, so it doesn't look much like a snowscape... but turned out beautifully nonetheless. I gave her 3 small dishes of salt- fine, coarse and rock- so she could explore the differences in each. It was such an interesting outcome... I imagine we'll be trying this again!
