DIY Lava Lamp




If you want to explore liquid density and chemical reactions, this is the science activity to try!


LAVA LAMP EXPERIMENT

To get started with your homemade lava lamp,  you will need 4 simple ingredients.


LAVA LAMP INGREDIENTS:

  • Water Bottles, Mason Jars, or Plastic Cups
    • We used a CORE water bottle 
  • Food Coloring
  • Baby Oil or Cooking Oil
  • Water
  • Alka Seltzer Tablets (generic is fine)
You might want to do this on a surface that you don't mind getting a little messy! 


         HOW TO MAKE A HOMEMADE LAVA LAMP

STEP 1: Gather your ingredients! 
STEP 2:  Fill your cup or jar(s) about 2/3 of the way with oil. You can experiment with more and less and see which one gives the best results. 


How else you can you change up this lava lamp science experiment? What if you didn’t add oil at all?  Or what if you change the temperature of the water?  What would happen?
STEP 3:  Next, you want to fill your jar(s) the rest of the way with water. These steps are great for helping your kids hone fine motor skills and learn about approximate measurements. We eyeballed our liquids, but you can actually measure out your liquids.

STEP 4:  Add drops of food coloring to your oil and water and watch what happens.

STEP 5:  Now it’s time for the grand finale of this lava lamp experiment! It’s time to drop in a tablet of Alka Seltzer. Make sure to watch closely as the magic starts to happen!


When the lava lamp chemical reaction slows down, add another tablet.
Hope you enjoy this little dose of chemistry and physics!
