All of the masses are in one cast

To change masses, change the frame
of the Flash member from 1–10.
Warning
The modal boxes for this and any other
activity doesn’t just appear, but floats
and fades in from the bottom of the
activity area. As it displays it bobs up
and down slowly by two or three pixels.
The box is dismissed and the sliders
are reset when the user clicks anywhere
in the activity area.
In cases where the text needs to be
changed, the font is sliderBold, 12/14pt
black.
Platform
The "hoists" move according to
therotation of the base platform.
A clockwise movement makes the
left hoist move up and the right hoist
move down the same distance, while
a counter-clockwise movement makes
the opposite happen.

Included is the same "start" animation from Act 1. This
button fires the selected particles into the seleced field,
and the fun begins.
Vector? I don’t even know her!
You may want to just use the cases I've provided in
Act_15.psd (I didn't put them in Elements) for the
five cases.
For magnetic fields, I have provided examples on just
the in/out cases. You can use the same vectors from
the electric field for the L - R magnetic field instances.

over the view window makes the particle bob
