Crystal Hearts
Here's a science experiment that your sweetheart will love!
Ingredients
Instructions
STEP 1: Twist a red pipe cleaner into the shape of a heart.
STEP 2: Using the thread, tie your pipe cleaner heart to the ruler. Place the ruler on thetop of the container to see if the heart floats freely inside the container.
STEP 3: Remove the ruler with the heart attached and add several cups of boiling water
into the container. Add about 1/4 cup of borax for every 2 cups of boiling water. Stir the
mixture until most of the borax is dissolved.
STEP 4: Place the ruler back on the top of the container allowing the heart to float in the
borax solution. Leave the heart in the borax solution overnight.
Explanation
Borax is a crystal. When water is heated, the molecules move farther apart. This makes
a lot of room for borax crystals to form. As the water evaporates, the crystals deposit on
the pipe cleaner creating a crystal heart.
