Product Details

Put a spin on egg decorating this year—add sparkling crystals! You’ll find everything you need to introduce crystallization and mineral formation with this unique and fun laboratory kit. Students apply the concept of solubility to create a supersaturated “growing solution.” After the eggs are coated with seed crystals, they are placed into a solution and left to sit overnight. Students will be amazed to find their eggs covered in beautiful crystals the very next day! After examining the crystals, students compare their egg geodes to how real geodes form in nature—a great multidisciplinary learning experience! Complete for 30 students working in pairs.
