Simple Salt Water Experiment
Sometimes all you need is a little table salt to entertain the kids.
To do this experiment fill two cups with water.
Dump salt into one cup and stir to dissolve it.
Predict what will happen when a ball is placed in both cups.
Place the ball in each cup and observe.
**If you get the same result in both cups try adding more salt or try a different ball (See first comment for more info)
