How To Make A Lava Lamp

I. INTRODUCTION A. Attention Getter: Have you ever caught yourself being hypnotized by a lava lamp? How the liquid separates and form different shapes and colors. Excited at the thought of owning one, but then you look at the price tag - and put it back.
B. Purpose Statement: Today I will show you how to make a lava lamp using common household items.
C. Preview Statement: I will be covering 2 points t. First, the materials and second, the 5 simply ways to make a lava lamp.

Transition: So now let’s start with my first point, preparing your materials for the project.

II. BODY

A. Materials: To begin you will need the following materials

1. 16-64 oz soda or water bottle
2. Bottle of oil
3. Bottle of water
4. Food coloring
5. Alka seltzer
6. Flashlight

Transition: Now that we’ve gathered our materials, we can begin with our steps to making the lava lamp.

B. There are 5 easy steps to making a lava lamp
Step 1: Fill the bottle 3/4 of the way full with vegetable oil then top it off with water and about 10 drops of food coloring (or enough to make the solution appear fairly dark).
Step 2: Cut an Alka-Seltzer tablet into pieces. You can either ration the pieces to make your lava lamp last longer or add more than one piece at a time for more interesting effects.
Step 3: Add pieces of the tablet to the bottle. This will cause the mixture to bubble. Repeat every time the bubbling stops. Unfortunately, with this type of lava lamp, the effects are temporary.
Step 4: Put the cap on and tip the bottle back and forth. This will cause the tiny droplets of colored water moving around inside the oil to join together, making bigger lava-squirt blobs.
Step 5: Place a strong flashlight or search light under the bottle. This will illuminate the bubbles for maximum effect. But don't leave your bottle on top of a heated surface! Plastic will melt and you'll get oil everywhere

Transition: Let’s go over what we did today

III. CONCLUSION
A. Summary Statement: You’ve learned an inexpensive way to make a lava lamp using 5 simple steps of mixing oil, water, food coloring and alka seltzer in a bottle.
B. Final Thought: I implore you to try making your own lava lamp at home with friends and family, not only will you enjoy the look of amazement on their faces but you will avoid going broke buying one from the store.
