Slice a small potato lengthwise into several pieces that each have two flat sides. Place some of the pieces in one dish and the rest in another. Fill both dishes with water. Add two tablespoons of salt to one of the dishes, and label it "salt water." Let the potatoes soak for 15 minutes.Compare the potatoes. Is there a difference in firmness? Why?
I predict:
Salt water will be firmer because it will go between the cracks. Salt water will join the potato.
What happened:
The salt water potatoes went softer.

Why don't I ever get it right!
