Lava Lamp at Home with Blobs in a Bottle

The multicolored blobs of a lava lamp can be quite fascinating to watch. How cool would it be to make something like that by yourself at home? Its a very simple science experiment which you can do with your friends at home. Make sure you ask your mom before you use the materials needed to make these blobs in a bottle from your kitchen.

And here is a list of the things that you will need for the experiment. One clear transparent plastic bottle. You can use a one liter cold drink bottle by taking off the label. One cup of vegetable oil, water, some liquid food coloring and a couple of fizzing tablets. You can use any effervescent tablet that is used for digestive purposes.

Use a funnel to pour the water into the bottle till its 3/4 full. Now add the vegetable oil to the bottle. Add about ten to twelve drops of the food coloring and wait for a while for the water and oil to settle down. Now add the fizzy tablet and watch the lava lamp effect come to life as blobs move in the bottle.

To make it even more fun shine a flashlight from the bottom of the bottle. As the tablet wears out you will need to add another one to keep the spectacular effects going in this science project.
