Siblings

In creating a simulation of balloons rubbing, I want to have ‘electrons’ created.
What tiles can I use to generate siblings or copies of a ‘dot’ that would then move around?
I’m not sure if I want siblings or copies......
This would be similar to having to create a stream of projectiles from a cannon or hose, for example.

You would use the electron's "copy" tile to duplicate it and the world's "include" tile to place it in the world, like so:

        world include electron's copy

(this actually produces a sibling, but it wouldn't matter either way)

Btw, since this is an Etoys-specific question, you may find this to be a better place to ask this kind of questions:

With siblings you can use 'tell all'-tiles, for example, with duplicates
you cannot.
