Science experiments are commonplace in our house, where my son has filled an attic “lab” with mysterious shampoo-based potions sealed in old jars. But few of these projects, Joe and I agree, have been as rewarding as the crystal-tree propagation we tried not long ago. Making the cardboard bases and setting them in a salt solution took just a few minutes. A day later, we were astounded by the mass of tiny crystals forming along the tree’s branches as the cardboard wicked up the solution. Two days later, we had a tiny enchanted forest, each tree fat with bristly spikes. Joe’s lab report: “It was worth the wait \u00e2\u20ac\u201d it was amazing!”<\/span><\/span><\/p>\n

\u00c2\u00a0<\/span><\/p>\n

The magic ingredient here is bluing, a nontoxic, old-fashioned laundry whitening product that helps the crystals form. We used Mrs. Stewart’s Bluing, which we picked up at the supermarket. To find it at a store near you, visit mrsstewart.com.<\/span><\/span><\/p>\n

\u00c2\u00a0<\/span><\/p>\n

Just for fun, we squirted some green food coloring on one of the cardboard bases before placing it in the bowl. The coloring was absorbed into the crystals, tinting them green, yellow, and blue.<\/span><\/span><\/p>\n

\u00c2\u00a0<\/span><\/p>\n

Our trees lasted about a week before they started to crumble. We tossed them in the trash when they were done (all of the ingredients are safe to discard). <\/span><\/span><\/p>\n

\u00c2\u00a0<\/span><\/p>\n

Materials <\/span><\/span><\/p>\n

Thin shirt cardboard <\/span><\/span><\/p>\n

Scissors <\/span><\/span><\/p>\n

Deep saucer or small bowl <\/span><\/span><\/p>\n

Small jar with a tight-fitting lid <\/span><\/span><\/p>\n

1 tablespoon table salt <\/span><\/span><\/p>\n

1 tablespoon bluing <\/span><\/span><\/p>\n

1\/2 tablespoon household ammonia <\/span><\/span><\/p>\n

\u00c2\u00a0<\/span><\/p>\n

To create the base, cut two cardboard tree shapes (about 4 inches tall and 3 inches across at the widest point). Cut a 2-inch slot in the top of one shape and in the base of the other. Join the shapes at the slots and stand the tree in a deep saucer or a small bowl. \u00c2\u00a0<\/span>In the jar, combine 1 tablespoon water, the salt, bluing, and ammonia (handling ammonia is a parent’s job). Fasten the lid and shake well, then pour the solution into the saucer or bowl. \u00c2\u00a0<\/span>Leave the tree undisturbed. Crystals may take as little as an hour or as long as a day to begin to form, depending on the humidity in your home (they’ll grow better in drier air). The tree will keep growing over the next few days, until all of the liquid evaporates.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
