How To Make a Lava Lamp - Nontoxic Version

Here's How:

1. This version of a lava lamp (unlike the real thing) is great for young kids! First, fill the jar about a third full of oil.
2. Next, sprinkle on glitter, sequins, small beads, or any tiny sparklies that catch your eye.
3. Add water to nearly fill the jar.
4. Add a drop or so of food coloring.
5. Finish filling the jar with water, then screw the lid on tightly.
6. Flip the jar over. Flip it back. Shake it up. Have fun!

Tips:

1. Let the liquids settle, then open the jar and sprinkle a tiny bit of salt on top. What happens? Why?
2. Water is a polar molecule, while oil is nonpolar. Polar molecules stick to each other, but not to nonpolar molecules. Oil and water don't mix!
3. The oil is less dense than water, so it floats on top.
4. Is the food coloring in the oil or the water? How can you tell? Is food coloring polar or nonpolar?
