“We have done several crystal projects using a borax solution, but it can be even simpler than that! We bet you already have exactly what you need for our gingerbread man salt crystal science project right in your kitchen! If you have some brown construction paper on hand, it makes for an easy gingerbread theme science activity! It is a simple activity to set up and complete. Note: The crystals will take a bit of time to grow.”
