Materials:

• Glass
• Salt
• Sugar
• Water
• Vegetable Oil

Instructions:

• Take a few glasses of room-temperature water and place them side by side. (Glass or clear plastic works best.)
• Add table salt to one glass, sugar to another and vegetable oil to the last one.
• Have your child mix each one.
• What happens to the things she added to the water?
• Have your child taste the salt and sugar water.
• Even though she can't see the salt or the sugar, it is still there.
• What about the water with the oil? Explain that water and oil are two substances that are immiscible -- they cannot mix together.
