Bubble or Bubbles. How to design bubbles by Illustrator? فقاعات

An Illustrator artwork showing bubbles

Bubble or Bubbles may refer to:

Physical bubbles

1- Liquid bubble:
A bubble is a globule of one substance in another, usually gas in a liquid. Due to the Marangoni effect[ is the mass transfer along an interface between two fluids due to surface tension gradient], bubbles may remain intact when they reach the surface of the immersive substance. 

Some Examples : 

• As water vapor in boiling water.
• As air mixed into agitated water, such as below a waterfall.
•  As sea foam.

 Its Appearance


Humans can see bubbles because they have a different refractive index (IR) than the surrounding substance.

2- Soap bubble:
A soap bubble is a very thin film of soapy water that forms a sphere with an iridescent surface. Soap bubbles usually last for only a few seconds before bursting, either on their own or on contact with another object. A soap bubble can exist because the surface layer of a liquid (usually water) has a certain surface tension, which causes the layer to behave somewhat like an elastic sheet. Soap film is extremely flexible and can produce waves based on the force exerted.

3- Antibubble:
An antibubble is a droplet of liquid surrounded by a thin film of gas, as opposed to a gas bubble, which is a sphere of gas surrounded by a liquid. Anti Bubbles are formed when liquid drops or flows turbulently( strongly ) into the same or another liquid.


Arts and literature
1- Bubbles (painting)
Bubbles, originally titled A Child's World, some artists likes the idea of bubbles and use it in drawing and designing artworks .

2- Speech balloon
speech bubbles, dialogue balloons or word balloons .They are a graphic convention used most commonly in comic books, comic strips and cartoons to allow words (and much less often, pictures) to be understood as representing the speech or thoughts of a given character in the comic.


Astronomy


Some examples

•  Local Bubble :is the cavity which contains the Solar System It is at least 300 light years across . 
• Superbubble :is a large structure created by multiple gases.It is the astronomical term used to describe a cavity hundreds of light years across filled with 106 K [ Kelvin is a unit of measurement for temperature ]gas blown into the interstellar medium by multiple supernovae and stellar winds. The solar system lies near the center of an old super bubble, known as the Local Bubble .

Economics 

Some examples
Economic bubble, a situation where market prices are unsustainable .

You can find the name of bubbles also in Film , Music ,Television ,Video games ,People and animals ,and Other .

I tried to design bubbles in an artwork . I had used illustrator for doing that.

الفقاعات
تشير كلمه فقاعه او فقاعات الى العديد من الاشياء منها 

الفقاعات الفيزيقيه مثل  

اولا   الفقاعات الناتجه عن اختلاط الغازات مع السوائل مثل
 فقاعات بخار المياه اثناء غليان المياه 
و زبد البحر  
 
ثانيا   فقاعه الصابون 
 وهي عبارة عن طبقة رقيقة من ماء الصابون لها شكل كروي وسطح متقزح أي يعكس ألوان قوس قزح المختلفة باختلاف الزاوية التي يرى منها السطح.
تدوم فقاعات الصابون لبضع لحظات قبل أن تختفى إما من تلقاء نفسها أو نتيجة ملامستها لجسم صلب 
  تعد عملية نفخ فقاعات الصابون من الألعاب المحببة للأطفال 

استخدمت الفقاعات فنيا فى الرسم و التعبير عن الفرح و الانطلاق للاطفال 
وكذلك استخدمت الفقاعات كرمز للتعبير عن الكلام او التفكير فى الرسوم الكاريكاتيريه والانترنت و غيرها 

إستخدامات مختلفه لكلمة فقاعات :
فى الفضاء و علم الفلك استخدمت كذلك كلمة فقاعه للاشاره الىبعض الظواهر الكونيه 

و كذلك استخدمت اقتصاديا للاشاره الى عدم استقرار السوق 
ولها استخدامات عديده فى الموسيقى و السينما و الكمبيوتر والعديد من الاستخدامات   

HOW TO DESIGN THAT ARTWORK? 
 Open a new illustrator document 400 X 400.

• Add new layer and draw a rectangle. Apply gradient color and no stroke.
• Add new layer for the background circles. With the Ellipse Tool, draw the circles with gradual decreasing sizes, and gradual increasing strokes. Start from outside and draw a circle 370 X 370 with 2pt stroke of lighter color and no fill, and then 350 X 350 and 3pt stroke, and so on ( 7 circles) or make the stroke size different  in a different way. With the shift key select all the circles and put them to the center, and then go to the Object menu, and select Group.  
• Add new layer for the lower gradient.

Add new layers for the symbol like bubbles. You can get it from the symbols panel. Put the bubbles in successive layers with gradual increasing opacity.  

• Add new layer for the spirals, and use the Spiral Tool for drawing it.
• Save your work.
