- - wide elastic;
- - sewing machine;
- - pins;
- - Mel (the remnant);
- - iron.
Advice 2: How to sew the lining to the skirt
- - scissors;
- - threads;
- - a sewing machine.
Advice 3: How to sew waistband to the skirt
- The main fabric, adhesive fabric, scissors, thread in the tone of the main cloth, pins, needles, ruler, chalk.
First you need to prepare yourself a belt. For this fabric the common thread cut out a strip width of 6-7 cm and make a raise in allowances of approximately 2 cm Length of the belt should be the waist and 7 cm, which have the allowances and on the zipper.
Advice 4: The wide application of electrolysis
What is electrolysis?
Electrolysis – it is a complex set of processes. In other words we can say that electrolysis is the migration and diffusion of ions. Also electrolysis include various electrochemical and chemical reactions occur between the products of electrolysis, between these products and the electrolyte, between them and the electrodes.
Not only for science is important to study these processes. Very important was the application of electrolysis in practice. For example, to thus obtain pure hydrogen, sodium and Nickel. Electrolytic processes are used for different purposes in the industry. So it is possible to obtain inorganic substances like oxygen, hydrogen, alkali, chlorine and other nonmetals.
Used electrolysis for purifying metals, such as gold and silver. Electrolytic processes lying in the basis of lithium, potassium, sodium, zinc, magnesium and other metals and metal alloys.
The application of electrolysis technique
The application of electrolysis technique consists in obtaining of organic substances, electroplating and coatings in the treatment of metal surfaces (electropolishing, boronovanii, cleaning and nitriding). There are also electrophoresis, electrodialysis, electroplating and other similar processes, which are used extensively in practice.
By electrolysis we can obtain one hundred percent pure metals. For example, copper. Copper ore contains oxides, compounds with sulfur and other impurity metals. The copper obtained from the ore, with all the impurities cast in plates. Then plate as the anode placed in a solution of copper sulfate (CuSO4). And then used electrolysis. To the electrodes of the bathroom is a bit of tension - and at the cathode stands out with the pure metal. All of the remaining impurities precipitate or pass into the electrolyte, not standing out at the cathode.
In the same way with the use of electrolysis to get aluminium. Here do not use aqueous solution. Instead, go in the course of molten bauxite. They contain aluminium oxide and iron oxide and silicon. After bauxite is treated with lye, a product called alumina. The alumina is immersed in a refractory furnace at the bottom and the walls which is lined with carbon plate. These plates are connected to minus power supply. To plus connect a carbon anode, passing through the wall of the furnace. When lowering the anode furnace is formed in an electric arc, molten alumina. Then this molten mass occurs electrolytic process and at the bottom of the furnace accumulate clean (up to 99.5%) aluminum, which is then poured into forms.
Advice 5: How to weave rubber band case for smartphone
For weaving a multi-colored cover with a picture diagonally need a machine for weaving from loom bands Rainbow loom, more than 200 PCs colored rubber bands and a well-lit workplace.
Take the machine out of the 12 pairs of columns and expand it to itself so that the hollows on the bars on the right looked forward, to the left of you.
For the first row take the 11 bands of the same color. Each elastic roll twice. Wear a rubber band on the machine in the form of eight diagonally from the first left column on the second right, etc.
Repeat a number of the opposite: from the first right column on the second left, etc. Should get a line crosswise. Pull the bands down to have a place for the other rows.
Take 12 rubber bands 2 of the same color. Wear them vertically on the left of the line in the usual way, to avoid twisting, combining two columns and alternating colors: six rubber bands of different colors, then six bands in the same color sequence. Latest elastic band worn horizontally, uniting the right and left columns.
The next row in the same colour scheme is repeated on the right lines. The last gum also incorporates the right column with the left.
Hook, remove the bottom band from each column to form a knot. Again, do the color number for the left line in the same sequence, skipping the first color (the image was obliquely). And so the circle. Remove the hook of the lower gum.
The following color wheel start with the third color, etc. After each mileage range remove the bottom elastic hook. The number of rows depends on the size of the phone, on average you will need about 33 rows.
Following the last round and removing all the lower bands, go back to the first left column. Place your hook in the bottom layer of the two rubber bands from the first left column and put it on the second left, the second to the third column, etc. From the last column of the gum are removed on the right side, and the braiding of the loops continues until the last right column.
In the last right column is necessary to make the fastening loop. Take the elastic and thread it through the bottom hook the elastic on the pole, tying it to the node. Carefully remove the remaining gum from the machine. Case ready.
