8. Magic Color-Changing Bath Salts
Turn bath time into an enchanting color-reveal spectacle with homemade magic bath salts. This craft is a wonderful sensory experience that involves layering different colored Epsom salts in a clear jar. Kids can mix Epsom salts with a few drops of skin-safe essential oils and skin-safe liquid colorants. The secret trick is to place a hidden layer of baking soda and powdered food coloring at the very bottom of the jar, topped with a layer of citric acid-infused white salts.
When the salts are poured into the warm bathwater, they create a delightful fizzing reaction, and the water magically transforms from clear to a vibrant, unexpected hue. Kids will love experimenting with different color combinations and observing how the colors blend and change right before their eyes, making it a stellar STEAM activity.
