Before adding the cardboard tree to the dish of magic crystal liquid, A painted the it with green food coloring. This is similar to the process that occurs in cloud formation. To make the crystal solution, my 5 year-old, A, simply mixed together all the ingredients in a dish: 4 tablespoons warm water. These minute particles act as nuclei, or seeds, for crystallization to take place. This guide is 100 working as of today so please make sure to watch thi. Stewart’s Bluing is a colloidal suspension of extremely minute particles of blue powder (Ferric Hexacyanoferrate). In this tutorial youll be learning how to get crystals and gold in Grow Castle 2021. The bluing and salt that remain can no longer be supported in the remaining solution and begin to crystalize. The final process, crystallization, occurred as the water and ammonia molecules leave the solution through evaporation. Once the solution travelled up the cardboard and evaporated, the next process could occur. The next process is evaporation, where liquid molecules escape from the solution as gas molecules.Īmmonia evaporates much quicker than water and we added it to the solution to speed up the evaporation process. This effect can be seen when a plant like celery draws up colored water through its capillaries, when paint is drawn up between the bristles of a paint brush and when porous materials like cardboard draw up water. In narrow areas, the combination of surface tension of water and the adhesive forces between the container and the liquid help to lift the liquid. Capillary action is the ability of a liquid to defy gravity and flow upwards. Our solid particles settled out on the cardboard tree due to a couple of processes.įirst, the liquid suspension is drawn up the cardboard tree through a process called capillary action. The solution we mixed up created a suspension, a mixture that has solid particles that are large enough for sedimentation (settling out). Ammonia (optional, but speeds up evaporation).Dish (large enough to hold your tree, with room for the crystal to grow).Cardboard (the back of a paper pad works best).Once my bluing arrived, I gathered my materials: I avoided the frustration of hunting it down and simply ordered it from Amazon here. (Other brands won’t work for this demo.)īluing is a laundry additive used to brighten whites and sometimes can be found in the laundry section of the grocery store. The hardest part of growing crystals, besides waiting, is finding the key ingredient, Mrs. This post contains Amazon affiliate links. The surprisingly simple experiment is the perfect addition to our top-selling Super Cool Science Kit! This crystal tree demonstration is no exception. No matter how many times we’ve waited for the stunning structures to appear, the surprise at what has grown never disappoints. There’s something magical about growing crystals – whether you’re growing crystal names or growing crystal trees.
