Frost experiment video tutorial
The following are the relevant contents of several frost-making experiments: ** 1. Dry Ice Frost Experiment ** 1. ** Material preparation ** - Dry ice, cut cans, disposable cups, thermos flasks. 2. ** Experiment Steps ** - He poured the dry ice into the can, then covered the lid and observed the outer wall of the can. In about a minute, a frosty substance would appear on the outer wall of the can. 3. ** Experiment Principle ** - Through this experiment, one could explore the source of frost formation. Some students would think that frost was transformed from dry ice, while others would think that it was transformed from water vapor in the air. He could touch the "frost" on the outer wall with his hand and found that the "frost" had turned into "water", which proved that the "frost" was directly transformed from the water vapor in the air when it was cold. ** 2. Frost Experiment with Ice and Salt (Iron Cup Version)** 1. ** Material preparation ** - Water, an iron cup filled with ice cubes, and salt. 2. ** Experiment Steps ** - The ice cubes in the iron cup were covered with salt to accelerate the melting of the ice cubes. - He poured the water from the cup into the iron cup. - After waiting for a few minutes, frost could be observed. 3. ** Experiment Principle ** - As the surface temperature of the iron cup with ice cubes was very low, the temperature of the air near the surface of the iron cup was relatively high. When there was a temperature difference between the air and the surface of the iron cup, the air would cool down when the warmer air came into contact with the colder surface of the iron cup. When the water vapor was saturated, the excess water vapor would be separated out. If the temperature was below 0°C, the excess water vapor would condense into ice crystals on the surface of the object, which was frost. ** 3. Frost experiment with ice and salt (stainless steel basin version)** 1. ** Material preparation ** - Ice cubes, stainless steel basin, salt, towel. 2. ** Experiment Steps ** - Put the ice cubes into a stainless steel basin and add salt to make them melt quickly (the principle is the same as snow melting agent). - During this process, the outer wall of the bottom of the stainless steel basin quickly cooled down, and the evaporated water vapor on the towel directly turned from gas to solid, condensing on the outer wall of the stainless steel to form "frost."

Hairdresser tutorial video
Here are some tips for hairstylists: - Scratching and Scissoring Method: - It was suitable for cutting layers, such as inverted wavy hair. To do this, comb all the hair high up to the top of the head and hold it tightly with your hands. However, this method of cutting hair would not be too long and would reduce the amount of hair, making the hair long and thin. It may not be suitable for people with thin hair. After that, he trimmed it according to his heart. He could pinch out a strand of hair at the hairline on his forehead to determine the position of the shortest hair layer, then return it to its original position, and then trim it from there. After that, he let go of his hair and combed it. Then, he grabbed the hair in the opposite direction and trimmed the scattered parts. Finally, he combed it again. - When cutting an elf's hair, if you want to grow bangs, comb out the bangs from the top of your head and trim it according to your preference. If you don't want bangs, you can comb all the hair directly to the top of your head and grab it tightly before cutting it. Your fingers will pinch the ideal length and cut it. Then, straighten the hair, pull out the thin hair layer vertically, and cut it vertically. Finally, continue to trim the remaining hair. You can refer to the hair area that you cut before as a ruler to complete the trimming. After that, you can also trim the edge of the tail. - High Ponytail Technique: - Keep your hair clean and moist before cutting it (if you have just washed your hair, spray it with a spray of clean water). You can bend down and lower your head or stand straight to comb the high ponytail. Comb the hair to the top of your head and tie it in the middle (you can use a mirror to determine the position). Use a rubber band to firmly tie the hair close to the scalp. Then tie another rubber band below the ponytail and cut it directly above the second rubber band (grab the end of the hair with one hand and cut the excess hair with the other). After cutting, loosen the hair and comb it. If the end of the hair is not neat, you can tie the ponytail high again for trimming. Pay attention to avoid hair that is slanted out. You can move the ponytail to make the hair flat. - There were also some who used a large comb and a large incision, cutting the top of the head in a shape that was long in front and short in the back, and the side area was long in the top and short in the bottom. The guide line can be vertically clamped upwards to make the front long and the back short layers appear. For super thick hair, it can also be cut into the shape of the front long and the back short, input it to raise it to determine the guide line and connect it, so that the front can be infinitely lengthened and finally trimmed short. It can also be fully opened and the upper cutter head can be hung up and down to form the inner layer. After the output, the outline can be trimmed. After cutting the front inner layer, press down to see if there is any extra long hair.

Shaving video tutorial
The following is a description of some of the operations related to shaving: - When Mr. Zhou shaved, he mentioned that the beard on the upper lip and chin was more difficult to deal with. When shaving the upper lip, he had to use the gap between his fingers to shave it clean, otherwise there might be residue at the root. When shaving the chin, he had to pull it with the thumb of his left hand. The knife in his right hand followed the thumb, and his left hand cooperated with his right hand. Because the beard on the chin was not easy to be still, more skills were needed when shaving. - When scraping the corner of the eye, if the eye mucus is obvious, after the eyelid is scraped, the eyelid can be opened and the knife can be used to remove the eye mucus. For the case where the hair at the corner of the eye is heavy, if you want to do a fine job, you can handle it. There is also the treatment of eye mucus in different positions around the corner of the eye. For example, if there is eye mucus at the corner of the eye in the eyebrow, the knife can be used to deal with it similar to the eyebrow. Pay attention to the distance between the positions, etc. However, there was currently no complete video tutorial for shaving. If you need a more detailed and accurate shaving video tutorial, it was recommended to search for a specialized shaving tutorial video through a search engine.

The accessories are standard covers. Light the background at the two o'clock direction on the back right side. To create a window effect, a window pane can be added in front of the light.] - "Assist light: Use another Shiniu Flash 600 second generation, and choose a long soft light box as the accessory. Light the main mooncake on the front right side. Pay attention to the position of the lamp head not to lean towards the background to avoid affecting the background light effect. - "Light fill: Use a large foam board to fill the light on the left side. If the shooting time is during the day and the fill light effect is not good, you can add natural light to make the light ratio more uniform. - ** Concept of composition **: For example, use the door as the background, place the main body on the table, arrange the props according to the rhythm of height, and use a flat angle to reflect the daily feeling. - ** camera parameters **: Aperture set to 5.6, shutter speed 1/160 seconds, USB 100, main light output 1/8, auxiliary light output 1/32. - [Post-production plan: adjust the white balance, increase the brightness of the shadows, increase the clarity and contrast, sharpen the outline of the props and the main body, and reduce the saturation of the blue primary color to reflect the dark atmosphere.] 2. ** Phone Shooting ** - ** Creating a sense of atmosphere **: Place the mooncake on a white plate, turn on the phone's 2x focal length (to prevent the plate from distorting), use some green plants as the background, and focus on the mooncake on the three-point line under the nine-square grid. - [Increase layering]: Take a book and place it under the plate. Use the top-down angle to center the composition. You can also place some cutlery on the side to form a parallel diagonal line. - ** Framed composition **: Break some mooncakes apart, take a cup, and use the cup handle to form a framed composition. The combination of virtual and real will create a sense of atmosphere. - Other techniques: Find a well-lit window, take two white rags, and pose the mooncake. Use the desk calendar as a prop to magnify it twice and make a diagonal composition. You can take a cup of tea as the background, click the portrait mode, adjust the aperture value to F2, and focus on the mooncake to create a sense of reality. You can also cut the mooncakes and stack them up and down. Find a magazine as the background, place the mooncake in a good position, magnify it three times and place the mooncake on the right three-point line. 3. ** Shooting in different styles ** - ** Simple Shooting ** - [Props: Various colors of cardboard. Melon seeds, walnuts, peanuts, and other common mooncake ingredients or grains may be used.] - ** Light **: Two lights to create a shadowless effect, shooting in the light. - ** Cameras and composition **: Aerial shot (God's perspective), using the golden ratio composition. - ** Chinese Style Shooting ** - Setting up the scene: Find a Chinese window pane and all kinds of old boards to set up the front and back. Find a Chinese vase that is similar to the color of the cheongsam and insert golden osmanthus. When the back is in space, you can hang calligraphy practice paper, pen rack, cast iron pot, etc. on the background cloth. Or use two boxes of mooncakes, a small porcelain plate, oil painting background paper, and a small table as props. You can also use two boards and a few old wooden trays. Add the four treasures of the study and tea set to create a Chinese atmosphere full of books. - ** Light distribution **: It can be used as a single bare light + standard cover, backlit on the right, and filled with light on the front left side. - ** Shooting method **: You can take a test shot, the photographer can take a selfie (such as a 10-second selfie after changing into a cheongsam after the scene is set up), take a close-up of the mooncake, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection experiment video explanation
The following are some of the relevant information regarding reflex experiments: - In the junior high school physics experiment "Reflection of Light", the purpose of the experiment was to verify the law of light reflection, namely, co-planar (reflected light, incident light and normal in the same plane), separation (reflected light and incident light are separated on both sides of the normal), equiangular (reflection angle is equal to the incident angle) and reversibility (the light path is revertible). The experimental equipment included a flat mirror, a laser pointer, a folded light screen with a scale, and a stand. The experimental steps included assembling the equipment according to the drawing, shooting a beam of light along the plane of the folded plate with a laser pen and recording the incident angle and reflection angle, changing the direction of the incident light to repeat the experiment, rotating the folded plate backward along the central axis of the folded plate to observe the reflected light, selecting an experiment to change the incident light in the opposite direction of the original reflected light to observe the reversibility of the light path, and finally sorting out the equipment to draw the conclusion of co-plane, separation, and equi-angle. - In the experiment of light reflection, the tracks of the incident light ray EQ on the cardboard could be seen from different directions because the light had diffused reflection on the cardboard. After changing the angle of incidence many times, the experiment could conclude that the angle of reflection was equal to the angle of incidence. When the light was directed against the OF direction to the flat mirror, the reflected light would be seen to shoot out along the OF direction, indicating that the light path was reversed. Cut the cardboard B along the PVP and fold the upper part of the cardboard B backward. During the experiment, the phenomenon of no reflected light on the cardboard B indicated that the reflected light, the incident light, and the normal were all in the same plane. - Reflection was divided into mirror reflection and diffuse reflection. However, this was only part of the reflection experiment. There might be other reflection experiments that were not covered. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
