Scientific Question:What happens when you add food coloring and fizzy tablets to water and

cooking oil?

Ingredients:• Food Coloring• Cooking Oil• ¾ cup of Water• Dry plastic bottle• Fizzing Tablets

Blobs in a Bottle

Steps

Pour the water into your bottle.

Now fill up the rest of the bottle with cooking oil. The oil has to separate from the water, so this might take a few minutes.

Add about 10 drops of food coloring (color is of your choice).

Break a fizzing tablet in half and drop the half tablet into the bottle. Watch it sink to the bottom and let the blobby greatness begin!

To keep the effect going, just add another tablet piece. For a true lava lamp effect, shine a flashlight through the bottom of the bottle.
