Combine the vinegar, water, dish soap and 2 drops of food coloring into the empty soda bottle. Use a spoon to mix the baking soda slurry until it is all a liquid. Eruption time! … Pour the baking soda slurry into the soda bottle quickly and step back!

First, add 1/3 cup of baking soda to your magma chamber (bottle). Then add about a teaspoon of dish soap for an extra foaming effect, and top it off with several drops each of red and yellow food coloring. Last, when you are ready for the action, pour in ½ to 1 cup of vinegar and watch the eruption.

Always keep the ratio one-part baking soda to two parts vinegar. The mixture will fizz and bubble, like your favorite middle school volcano science project.

Here is a step-by-step guide to performing the volcano science experiment with your kids.

1. Step 1: Mix the dish soap, water, white vinegar, and food coloring and pour it into the empty soda bottle.
2. Step 2: Make a baking soda slurry with ½ cup baking soda and ½ cup water.
3. Step 3: Now, it’s eruption time!

. Since have done our fair share of science experiments for kids, especially ones with eruptions the children were quite familiar with the process. Adding half a cup of apple cider vinegar to the baking soda gave us some cool apple scented eruptions. …

Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. This lighter magma then rises toward the surface by virtue of its buoyancy.

Once ejected into the atmosphere, the sulfur dioxide spewed from volcanoes can react to form sulfate aerosols, which are tiny particles suspended in the air. Both ash and aerosols can scatter the sun’s rays, giving a sunset its apparent color. And under certain circumstances, purple sunsets will result.

When you look up at the sky, any light that you see has been redirected toward your eyes—it has been scattered. Because you are seeing only scattered light, the sky appears blue. But violet light has an even shorter wavelength and a higher frequency than blue light, so by all accounts the sky light should be violet!

Originally Answered: Why does the sky turn pink in the evening? Because the sun is low on the horizon, sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes.

When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically good weather will follow.

Red, orange and pink clouds occur almost entirely at sunrise and sunset and are the result of the scattering of sunlight by the atmosphere. The clouds do not become that color; they are reflecting long and unscattered rays of sunlight, which are predominant at those hours.

Thunderstorms, which can be the home of tornadoes, usually happen later in the day, when the sun is approaching the horizon. That creates a reddish tinge in the sky, as any fan of sunsets knows. But light under a 12-mile high thundercloud is primarily blue, due to scattering by water droplets within the cloud.

When a particularly strong storm hits (whether it’s a typhoon, cyclone, or hurricane), the skies can take pinkish or violet hues. Heavy storms push away the larger molecules which scatter wavelengths more evenly. This makes the colors of the sky appear more vivid, but that’s just a part of it.
