If you found an ad for this instructable in the back of a comic book, it would read something like:
"Amaze your friends by growing a crystal tree out of common table salt and a few other ingredients available from the grocery store"
Step 1: Gather Your Materials
- Mrs Stewart's Bluing
- Table salt
- Household Ammonia (the kind with no soap added)
- Cardboard (not corrugated)
- Measuring spoon
- Food Coloring (optional)
The bluing is the hardest item to find but can be found in the cleaning section of many grocery stores. You can find the ammonia close by.
The cardboard I used came as packing material from a new shirt, or the backing from a paper notepad. Cereal box cardboard might work, but it's thinner & has printing on one side...
Depending on the temperature & humidity of your location, the ammonia is optional, but speeds up the crystal growth -- the tree in this Instructable started "sprouting" in less than an hour. Without ammonia, it may take a couple of days to start.
