Grow bright orange potassium dichromate crystals. Choba Poncho. Grow naturally blue-green crystals from copper acetate. This is a chemical you can make by reacting vinegar and peroxide with pennies or copper wire or you can find the pure chemical online. These crystals exhibit an interesting shape and gorgeous color. Easy Color Change Crystals. Light and temperature shift the color of these crystals between yellow, green, and blue. Eigenes Foto. This is like a mood ring, except it grows different shapes of crystals rather than changing colors.
Does it actually predict your mood? Learn how to make quartz and other translucent crystals glow in the dark. The technique relies on phosphorescence , so once the crystal is exposed to light, it stores the energy and releases it as different colored light.
You can get a crystal to grow all night long. Grow solid black or translucent black crystals by either dying the crystal-growing liquid or using a black base beneath clear crystals. Mike Beauregard. Crystal Flower. Actually, you could preserve a plastic or silk flower too, but where this project really shines in in preservation of real flowers.
It could be a flower from a special event or from your garden. Crystallizing it is a way to make it last forever. Maple Syrup Crystals. These edible crystals are a type of sugar crystal that grows from maple syrup. You can use the same technique to grow corn syrup crystals, too. Salt Crystal Geode. Nature takes thousands of years to produce a geode, but you can make one overnight.
Your geode will consist of real crystals on real minerals, plus you can customize the color. Glowing Geode. Add a simple ingredient to turn an ordinary crystal geode into one that glows in the dark or glows under black light.
Borax Crystal Heart. Crystal Egg. Grow crystals on the surface of an egg for a decorative Easter project or simply as a beautiful ornament. You can hollow out the egg first or grow crystals on a raw or boiled egg.
If you use table salt for the crystals, you can eat the crystal egg, too. Once the string has dried, tie the clean end around a pencil and put the dipped end back into the glass of sugar water solution, balancing the pencil across the rim of the glass.
Make sure the string does not touch the bottom or the sides of the glass, or your crystals will not form right! Fill a glass with water, pour some sugar on a small plate, and lay out a sheet of waxed paper. Dip one end of each stick cut pointed ends off if you use skewers into the water and then roll it in the sugar, tapping it gently to remove excess.
Set each stick to dry on the waxed paper. Stir it well until no more sugar will dissolve. You now have a saturated sugar solution. Ask an adult to help you heat the sugar mixture on the stove until it boils, stirring the whole time. Turn the heat to medium-low and keep stirring until all the sugar dissolves.
Now you have made a supersaturated solution! Keep cooking the liquid and stirring it until it becomes clear, but not for more than 5 minutes, or it will get too hot and turn into hard candy! Turn off the stove as soon as it starts to look clear. Move the pan off the heat and allow it to cool down until the pan is no longer hot the sugar solution will still be slightly warm. Have an adult slowly pour the thick sugar solution into the jars.
Add drops of food coloring to each jar and stir. Optional: Only do this step if you want to make different colors of rock candy! Once the solution is cool and the sugar-coated sticks are completely dry, place several sticks into each jar. Check them every other day and gently stir the sticks around in the sugar solution to break up any large crystals forming on the surface.
Within a few days, you should start to see crystals growing on the sticks. After about one week, you will probably have a lot of crystals.
Once they are dry, you can wrap in cellophane food wrap and tie with ribbon for a sweet Christmas gift! Once the saturated solution started to heat up, the water was able to dissolve even more sugar and a supersaturated solution was formed in step three. Then, as the solution cooled, the sugar molecules in it started to join with the sugar molecules on the sticks.
Meanwhile, the water in the solution started to evaporate or dry up into the air, leaving only sugar molecules behind. More sugar molecules gradually joined with the ones already on the stick, forming larger crystals. Because all of the solute molecules are the same they are all sugar , they all form the same shape of crystals and they all stick together, making a big chunk of sugar crystals that are pretty to look at and tasty to eat!
Note that this is a special science project that is safe to eat because you only used food products, not chemicals. Plus, you used clean dishes from your kitchen. Never eat any experiment unless it is made entirely out of food and you only used clean dishes to prepare it! In this project, you use a chemical called Borax to grow crystals shaped like snowflakes, stars, or candy canes.
Then you can use them as pretty decorations! Note: Make sure your pipe cleaner shape will fit easily into your jar with plenty of space around the mouth of the jar as the shape will be slightly wider once crystals have formed on it, making it harder to remove! Tie a piece of string to one point of the shape. Tie the other end around the middle of a pencil. Hang the shape in the jar with the pencil resting across the mouth of the jar.
Make sure that it hangs without touching any part of the jar. Crystallization can be beautiful and delicious! It all depends on the circumstances. Caution : Borax can be harmful if it comes into contact with eyes, inhaled or ingested. It may also irritate skin. These experiments are not to be done with small children and protection is recommended including safety glasses, gloves and even a face mask to prevent irritation. During our experiments I alone worked with the borax powered, adding it to the water to create our solution.
All other aspects the children were able to be active participants. Safety always comes first. First, build your shapes from the pipecleaners. We went with some hearts plus some fun, abstract designs. You want to keep the gaps to no more than a small finger width. This will help in crystal formation. Once your shape is created attach it to your skewer using the fishing line.
The national chain stores do not usually have it, but many of the local stores do. You can call and ask what stores in your area carry washing soda. Use caution when boiling water. Activity First, you need to know a little bit about the conditions for growing crystals and why they grow. This will allow you to make your own modifications to the process to get the best crystals. All crystal making begins with a saturated solution.
This is simply a solution that cannot hold any more of the material. For example, if you are making a saturated solution of salt water, you would add salt to the water until no more could be dissolved. Eventually the salt will start collecting on the bottom of the container because the water cannot hold any more salt. Crystals grow when the solution becomes supersaturated , meaning that there is too much salt dissolved in the water.
The extra salt or other material takes the form of crystals. To get a supersaturated solution you can either cool down the solution or let some of the water evaporate.
To begin, make some Epsom salt crystals. These are easy to grow and you will begin to see crystals in a couple of hours. Start with one cup of warm distilled water not boiling. Start adding Epsom salts by the spoonful and stirring until they dissolve. Continue doing this until not more Epsom salts can be dissolved this will probably be about one cup.
Let the mixture sit for a couple of minutes until all of the undissolved salt is on the bottom of the container. Slowly pour off the solution into a shallow bowl, but stop pouring before you get to the undissolved salt. Put the bowl in the refrigerator for 3 hours.
