Crafting your coffee step-by-step guide
You can easily make coffee at home using either method. Geek out with equipment and exact times and temperatures if you want, or just follow the basic steps.
1. Buy newly-roasted, high-quality coffee in small quantities, so it's fresh.
2. Grind the beans just before making the coffee, ideally in a burr-type grinder that creates a uniform grind somewhere between the texture of sugar and flour. There are electric burr grinders, or you can use the Hario manual grinder.
3. Weigh the ground beans for the most exact measurement, or just measure by volume.
4. Put a paper filter in the top of the holder. The Chemex pot is an all-in-one glass beaker, shaped like an hourglass, and the top holds the Chemex filter, squares of high-density microfiber paper. The Hario filter holder is cone-shaped, with ridges that curve down toward one star-shaped hole at the bottom. The ridges create turbulence and keep the coffee from sticking to the side. Pour boiling water through to rinse and wet the filter. Throw that water out. (This keeps the flavor of paper out of the coffee and warms the pot or cup.)
5. Put the ground coffee in the filter.
6. The proportion of water to coffee is obviously very important. You can experiment with it for each coffee, and for your taste. To get it perfect, use a scale, and start with 20 grams of beans for 12 ounces of coffee. You put the whole set-up on the scale, zero it out, and then add water by weight. But you can, more simply, use a volume measurement.
7. Bring water to a boil, then pour it into a Hario Buono kettle, which looks a little like a watering can, with a long pouring spout. It should be between 195-205 degrees. You can also pour straight from a regular water kettle, but that doesn't allow for as much control.
8. Wet the grounds with some of the water (15 percent of the total water you'll use, to be exact) Let it drip through for about a minute. This "blooms" the coffee, releasing gases and allowing for more even extraction of the beans.
9. Here's the heart of the method, and the part that takes patience: Slowly pour the rest of the water in a circular motion in the middle of the coffee. (Pour clockwise, in the case of a Hario, because of the curving ridges on the holder) through the ground coffee, keeping away from the edges. It will take about 3 ½ minutes to pour the water and let it drip through. The idea is to keep the grounds from packing down at the bottom of the cone, allowing for even extraction. Use the scale to know when to stop.

Fantastic colors chemical change "PLASMA" Fountain of the experiment, you can do at home with some help from a couple of pretty boys. Here's a favorite of many chemical experiments, that my brother Adam and I, John designed and shown to people when they visited our laboratory Kew in the late 70s to early 80s. A sort of precursor and inspiration for this lamp plasma, we have but that is chemically dissolved. This is my original review from an earlier form of this experiment in 1979, whenI was 11 years old, who has developed a bit 'over time. Never forget the scientific method! Now I have some fun showing my kids. We start with the juice of red cabbage. Here is the procedure for the juice of red cabbage. Please have an adult to help you with every step. 1. Chop a red head cabbage and put in a pot. 2. With boiling water poured over the cabbage and cook the mixture. 3. After about 10 minutes Pour the mixture through a sieve or strainer into another container. Pour into a large extentCup. 4. Throw away the used cabbage. 5. If you are not the entire amount of cabbage juice and want to save it for later, put it in a sealed container in the refrigerator. If you want to keep longer, you can freeze the liquid in ice cube trays e. If the juice of red cabbage, you're ready to test the pH of various substances.
