How To Draw A Lava Lamp Step By Step
Lava Lamp
Materials:
- A clean plastic bottle, try to use one with smooth sides
- water
- Vegetable Oil (or yous could use Mineral or Babe Oil instead)
- Fizzing tablets (such as Alka Seltzer)
- Food Coloring
Spotter Scientist Joe as he makes the Lava Lamp Experiment hither!
Instructions:
- Fill the bottle up about 1/4th (1 quarter) with h2o.
- Cascade the vegetable oil in the canteen until is almost full. You may want to employ a measuring cup with a spout or a funnel. Yous may take to wait a couple of minutes for the oil and water to separate.
- Add a few drops of your favorite food coloring. Spotter as the color sinks through the oil. Did your drops of colour mix with the h2o immediately or float in between for a few minutes?
- Interruption your fizzy tablet in half and drib role of it into the bottle. Become gear up … here come the bubbly blobs!
- Yous can even go a flashlight, turn off the lights and drop in another half tablet. This fourth dimension shine the flashlight through the lava lamp while the blobs are bubbling!

How it Works:
The oil floats on top of the water because it is less dumbo or lighter than h2o. The nutrient coloring has the same density equally the water then information technology sink through the oil and mixes with the water. When you add together the tablet it sinks to the bottom and so starts to dissolve. As it dissolves information technology makes gas, carbon dioxide. Gas or air, is lighter than water so it floats to the meridian. The air bubbles bring some colored water with them to the meridian. When the air comes out of the colored h2o hulk, the water gets heavy over again and sinks. It does this over and over again until the tablet is completely dissolved.
Extra Experiments:
What happens if you lot put the cap on after dropping the fizzy tablet in? What if you drib a whole tablet in? When it stops bubbling, endeavor sprinkling some salt into your lava lamp. What happens?
