Full Step-by-Step
1. Prepare the Base
- Shape Trees: Bend pipe cleaners into a tree shape for the trunk and branches. Secure them in a jar.
- Cover Surface: Line a baking tray with parchment paper or aluminum foil to catch overflow.
2. Make the Solution
- Mix Ingredients: In a bowl, combine 1 cup of baking soda with 1/2 cup of vinegar. Watch the fizz! This reaction creates carbon dioxide and will help the crystals grow.
- Color It: Add a few drops of food coloring to the mixture, stirring until well blended.
3. Create Crystals
- Pour Mixture: Carefully pour the colorful baking soda mixture into the jar, soaking the pipe cleaner tree.
- Settle: Place the jar on the lined baking tray to catch any spills. Let it sit undisturbed for several hours to overnight.
4. Observe Crystals Forming
- Check Back: After a few hours, check the tree. You should see beautiful crystals starting to form.
- Display: Once complete, gently remove the trees and place them in a sunny spot to showcase their sparkle.
Tips & Variations
- Color Blends: Mix different colors of food coloring for a marbled effect.
- Different Shapes: Use various shapes of pipe cleaners or even straws to create unique trees.
