How-To Make Lava Lamps
We got everything at Dollar Tree, to make it affordable! You can choose to do one or two as a whole class demonstration, or buy the see-through plastic reusable cups so there’s enough for every student to make one. You’ll need:
- Clear Containers (mason jars, plastic cups, vases, or have parents send in empty 2-liter bottles!)
- Baby Oil (You can also use vegetable, olive, or canola oil)
- Acrylic Paint or Food Coloring
- Alka Seltzer Tablets
- Dry Erase Marker for Decorating
Just a few simple steps and you’re ready to amaze your students!
- Decorate your container with a fun Halloween theme! You can draw a pumpkin face, Frankenstein, a ghost, spider legs, or just use fun stickers…the possibilities are endless!
- Fill the container about halfway up with your oil of choice.
- Mix another small container with water and either paint or food coloring.
- Pour the colored water into the oil. This is a great time to talk about why the oil and water separate, and have students make predictions on what they think will happen!
- Break Alka Seltzer tablets into small pieces and drop them in one by one and then watch the magic happen! Your students will LOVE it!
