LAVA LAMP
Materials:
​
A clean plastic bottle, try to use one with smooth sides
water
Vegetable Oil (or you could use Mineral or Baby Oil instead)
Fizzing tablets (such as Alka Seltzer)
Food Coloring
Fill the bottle up about 1/4th (1 quarter) with water.
Pour the vegetable oil in the bottle until is almost full. You may want to use a measuring cup with a spout or a funnel. You may have to wait a couple of minutes for the oil and water to separate.
Add a few drops of your favorite food coloring. Watch as the color sinks through the oil. Did your drops of color mix with the water immediately or float in between for a few minutes?
Break your fizzy tablet in half and drop part of it into the bottle. Get ready … here come the bubbly blobs!
You can even get a flashlight, turn off the lights and drop in another half tablet. This time shine the flashlight through the lava lamp while the blobs are bubbling! STORM IN A GLASS
