In creating a simulation of balloons rubbing, I want to have electrons¹ created. What tiles can I use to generate siblings or copies of a dot¹ that would then move around? I¹m 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.

'Tell all siblings' is in my experience much prefered if I am simulating lots of similar objects moving around eg. bouncing atoms.
My aging computer will feel unreponsive if I try to make a few hundred copies of a moving atom when each has a ticking script.
