    Salt Water Experiment: Did you know that it is easier to float in the ocean than in the swimming pool? Do you know why? Salt. The ocean is full of salt. Salt water can hold up more than plain water. That is why you can float in the ocean more easily. Try this experiment to see for yourself. You'll need:

    *2 clear, wide mouth, plastic jugs or jars
    *9 cups warm water
    *1 cup salt
    *raw potato
    *measuring cup
    *spoon

    Pour 4 and 1/2 cups warm water (half of the water) in one jar and add salt. Stir with spoon until salt has dissolved. Pour the other 4 and 1/2 cups of warm water (last half of the water) in the other jar. First put the potato into the jar without the salt and watch it sink. Then put the potato into the jar with the salt and watch it float.
