Family Science: Bath Salts

 Let’s make bath salts.  We used this recipe with vanilla extract.  How do you make this into a science experiment?  Test different recipes.  This recipe uses washing soda or sodium carbonate with a little oil and food coloring.  Let your child research several recipes, such as this one with Epsom salts and sea salts.  Instruct your child to try baking soda, Epsom salt, and sea salt separately in bowls of water.  Combine two of each in water.  Which combination seems to work best?  Is there a significant difference?  See?  This is science.  We packaged our salts into small bags for presents.
