DIY Lava Lamps

Interested in making your own "lava lamps" at home? It's super simple!

You will need: 

• Water
• A Clear Plastic Bottle 
• Vegetable Oil
• Food Coloring
• Alka-Seltzer Tablets (split into 4 pieces)
• Glow Sticks (Optional)

Directions:

1. Fill the plastic bottle 1/4 to 1/2 full with water.
2. Using a funnel, fill the remainder of the bottle with oil. (Be sure to leave a little air at the top.)
3. Add 4 to 6 drops of food coloring. 
4. Add one piece of alka-seltzer to get the lava lamp "going". Add in more tablets as the bubbling begins to diminish. 
5. Add a glow stick for an extra bit of fun.
