Bubbles

Bubbles sends a steady stream of soap-like bubbles rising from a point, each with a thin coloured film that shifts as it catches the light. Near the end of its life a bubble swells, flashes and pops.

How it works

Bubbles are released from a small spot at the effect's position at a set rate, each with a slightly different size, speed and sideways push. They rise, lose their sideways drift and wobble gently as they go. Every bubble is drawn bright at its rim and nearly clear in the middle, with a small highlight, so it reads as a hollow sphere. The rim colour cycles through three colours you choose, which imitates the shifting bands of a soap film. In the last part of its life a bubble grows to more than twice its size and flashes before it vanishes.

Settings

• Colors: the three film colours the bubbles cycle through.
• Iridescence: how much the colour shifts. At 0 every bubble takes the average of the three colours.
• Spawn Rate: bubbles per second.
• Float Speed: how fast they rise.
• Lifetime Ms: how long each bubble lives before it pops, in milliseconds.
• Scale: bubble size.

Use it for

Underwater scenes, fizzy drinks and carbonation, bath and beauty products, playful kids' scenes. The Bubbles cursor and the Bubble trail object effect carry the same idea.
