## WHAT IS IT?
A model of table salt (sodium chloride, NaCl) dissolving in water.
## HOW IT WORKS
Molecules wiggle around. When an NaCl molecule (white triangle) meets a water molecule (blue circle), it dissolves into an Na+ ion (green square) and a Cl- ion (yellow star).
## HOW TO USE IT
Clear button - clears the world and plots
Add NaCl button - adds NaCl concentrated near the center of the field
Add water button - adds water scattered throughout the field
wiggle-angle - When molecules move, they take a random left turn of up to wiggle-angle, then a random right turn of up to wiggle-angle. What does changing the angle do?
Molecules by Time plot - plots the number of solid NaCl molecules and the number of dissolved Na+ and Cl- ions at each time step.
