One of my absolute favorite digital toys is the particle bubble. If you want to do this, click on Easy Palette, particle gallery, Click on the plus sign and navigate to Bubbles.
Your options will be different depending on what version you are using. Of course, you may pick any of the bubble groups. They vary in quantity, size and reflective qualities, and of course, each may be applied directly to your canvas or modified like we're going to.
R/C on "Bubbles 12" for PI7 or 8, or "Bubbles 6" in PI 5 or 6, then choose "Modify Properties and Apply".

From this menu you may adjust the Effect Controls:

• Density - Quantity of bubbles from 1 to 100.
• Size - From 1 to 100 percent
• Variance - Controls the range of variability in size
• Reflection - Increase from 0 to 100.
  

It is important to remember that the controls will change every bubbles characteristics if none is selected. And you can select more than one bubble.

In the particle dialogue box below, the density is 4, the size is 51. You can see from the examples below the dialogue box, there are many different ways of playing with the bubbles..The importance of experimenting can't be repeated enough. When you 're pleased, then press the OK button.
