Physical Science Thank you for your input. In both cases, you need two things: How can we use chemicals to make a rainbow in a jar? Carefully pour it into the bottom of your jar.
But what is it? When the pressure of a gas falls, then its temperature also falls the same principle as is used by your refrigerator. The reduced temperature cause small drops of water to condense, which then may freeze. The frozen drops get larger as more water condenses on them.
A rather more scientific explanation also explaining the exact colors can be found here: They need a lot of moisture, and cold air is generally dry, so they are more common in the summer months, and in warmer climes. As aerodynamic contrails are independent of the formation conditions of jet contrails, they form an additional class of contrails which might be complementary because they form in predominantly in layers that are too warm for jet contrail formation.
They are not entirely complementary however, as you can get both types of contrail simultaneously from the same plane, see below. There is actually surprisingly little work being done on the formation of aerodynamic contrails.
A lot of the time they only show up as wingtip contrails which you can see are very dense in the above photo. Conditions need to be just right for the full wing to generate a contrail, and it typically does not last very long at all.
Here you can see the wing contrails vanish almost immediately. If the aerodynamic contrail is thick enough, then it forms like a solid sheet, and can curl up at the sides as it is drawn into the wingtip vortices: I suspect that the shadow you see near the tail is actually the shadow of the plane on the clouds, meaning the plane is just above them, or in them — in a region of high humidity, either way.
From the same set, we can see that the two types of contrail are not mutually exclusive. You can have both at the same time: Note you have the thick white contrails coming from the engine, and the aerodynamic contrails coming from the wings. In most of the shots, you can clearly see the type of plane, and usually the airline markings.
This video shows an aerodynamic contrail forming in patchy air: Aerodynamic Contrail in patchy air You can see the trail looks very similar to the photos, especially in the final segment of the video.
Note this video was shot in Torino TurinItaly ,on August 16th — during the summer. This is taken at a lower altitude, with the the sun just right.Easy Science Projects.

Science for kids ages 2 and up.
We love fun kids’ science and this easy activity is one of our favorites. With just a few common household ingredients like dish soap and honey, little scientists can actually pour a rainbow in a jar.
