Growing Crystals

When I was a boy I discovered the magic of growing crystals from various ingredients. That was shortly after I was disappointed when my Sea Monkeys didn't look at all like monkeys. And my X-Ray Specs didn't work like they were supposed to, either. So I started growing crystals in my little bedroom laboratory.

I used salt, sugar, and alum. Each of these composites will produce crystals with different structures. The salt crystals are always cubic. The sugar (which you could eat after they formed) are hexagonal with pointed ends. My favorite was the crystals produced with alum. In case you have a youngster, or a grandchild, this might offer you an opportunity for some quality time and a learning experience that could spark an interest in chemistry or science.

Just so you know, alum crystalizes in a tetrahedral form. The crystals form like two pyramids joined at the base.The photo above is of a chrome alum crystal. I'm not sure what chrome alum is, but the crystals you can grow from regular alum look just like this except they are clear instead of black. Below is a step-by-step procedure for turning common, white alum into beautiful, clear crystals that look like sparkling diamonds. What you need to do first is to create what is known as a super-saturated solution. More material (salt, sugar, alum) will dissolve in hot water than will dissolve in cold. The higher the temperature, the more will dissolve and the more saturated the solution becomes. So here we go . . .

Step 1: If you don't already have some, go to the grocery store and buy a box of alum. You'll find it in the baking section or with the spices.

Step 2: Place a sauce pan containing one quart of water on the stove and turn it on.

Step 3: As the water starts to heat, begin pouring the alum into it, stirring with a spoon as you add it. Not too much at a time. Make sure it's all dissolved before you add more. Continue adding the alum until no more will dissolve. Try to keep the water temperature just a little below the boiling point.

Step 4: After the water has cooled a bit, pour it into a a quart jar and leave it alone for a few hours.

If you've created a super-saturated solution, the alum will begin to form crystal within 24 hours. You will see them forming on the bottom of the jar like tiny diamonds. There will probably be several of them, so we want to remove a lot of them to give the others more room to grow. Otherwise you will end up with a "matt" of crystals on the bottom of the jar. And that's not what you want. We're trying to create three or four really nice crystals.

Step 5: In a day or two your crystals will have grown to 1/8 inch or so across. Get a long pair of tweezers and remove all of the small crystals. If you don't have a long pair of tweezers you can pour the solution carefully from your incubator jar into another container and then remove the crystals with a spoon. Examine them and pick a half dozen or so of the biggest or best-formed ones and set them aside. Then pour the solution back into the jar and add your selected crystals. Try to arrange them so they're not touching each other.

Step 6: You'll need to turn your crystals every day so that the alum is added to each side equally.

IMPORTANT NOTE: Do not place a lid on the jar. If you do, the water can't evaporate.

Evaporation is important so that the solution remains at a constant state of saturation and your crystal continues to grow. If you notice that your crystals look smaller than they did the previous day it means the saturation level has decreased and the water is dissolving the alum from your crystals. If this happens, remove your crystals and create a new solution as explained in Step 2. But don't place your crystals back into this new solution until it has cooled to room temperature. Otherwise it will dissolve. Keep making new solutions as your crystal continues to grow until you get it to the size you want. Then you can take it out of the jar and put it on display. The air won't hurt it. Just don't let it get wet because alum dissolves in water in both the powdered and the crystal form.

Having written this, it makes me want to do it again. I'm going to go buy some alum. Have fun! If you have any questions, leave a comment and I'll try to answer it.

The Dreaded Brain Freeze Explained

Most of us have had them. It's something you don't forget. One minute you're enjoying your favorite frozen beverage or ice cream cone, and the next minute you're experiencing an excruciating headache which seems to originate from the middle of your skull. This is the dreaded phenomenon known as "brain freeze," or ice cream headache. Some experts suggest that up to 1/3 of the population is susceptible to brain freeze, especially when eating a frozen treat too quickly on a warm day. The pain of brain freeze is similar to that of a migraine headache, but thankfully most attacks last 30 seconds or less.

So what actually causes brain freeze? Researchers suggest it is a combination of your body's overreaction to cold stimuli, freezing of a cluster of nerves above the palate and a sudden influx of warm blood to the brain. Eating all of that ice cream or slushy drink too quickly didn't help matters, either. In fact, it was the initial contact between the cold food and the roof of your mouth which set all of this brain freeze activity in motion.

When you took an extra large bite of ice cream, some of it reached the roof of your mouth, also known as the hard palate. Behind this hard palate lies a cluster of nerves which act as a protective thermostat of sorts for your brain. The main nerve is called the sphenopalatine nerve, and it's extremely sensitive to abrupt changes in temperature. Once the ice cream or other frozen food causes the sphenopalatine nerve to cool down, it sends out a warning to the other nerves in the cluster. Essentially, your brain has now been told to expect a major freeze, so it had better prepare itself.

Your brain doesn't actually freeze during a "brain freeze" episode, but the sphenopalatine nerve cluster didn't know that at the time. The blood vessels surrounding the brain suddenly shrink as a reaction to the cold stimuli, or more precisely overreact. The result for you is a pounding headache which seems to radiate from the sinus area or behind your eyes. The pain is not necessarily triggered by the dilation of the blood vessels, but by the influx of warm blood which forces the vessels open again.

While all of these blood vessels are busy shrinking and reopening with warm blood, the nerves are also contributing to the pain of brain freeze. The pain receptors near the sphenopalatine nerve cluster sense the freezing of the palate, but the pain itself is referred to another area deeper in the skull. This is why you feel brain freeze deep inside your head and not in the roof of your mouth.

One of the quickest ways to reduce the duration of brain freeze is to place your tongue on the roof of your mouth to warm the palate. Once the palate becomes warm again, the nerve clusters are no longer stimulated and they will call off the brain freeze warning. Drinking sips of warm water will also minimize the effects of brain freeze, as will eating frozen foods slowly and avoiding contact with the roof of your mouth.
