Home Made Lava Lamp

What you're going to need for this experiment is :

  • An empty bottle
  • Cooking oil
  • A small box 
  • A torch 
  • Some food dye 
  • Some alka-seltzer 
  • A funnel and 
  • Water
First of all take your water and your funnel and very carefully pour some water into your bottle. You need to fill the bottle about a quarter of the way up. Then take your vegetable oil and using the same funnel pour into the bottle. You'll see that the oil sits on top of the water. This is because oil is less dense than water.

 Then take your food dye. For this experiment I have chosen to use blue is my favorite color. Place some food dye inside the bottle. You'll see that it immediately goes straight through the oil and into the water. Then take out your alka seltzer, break up one of the tablets and drop them through the neck of the bottle.

 As they pass through the oil and hit the water they started melt. The bubbles from the reaction then passes through the oil carrying the food dye and the water with it creating colored bubbles.Is not it great? 

If you want to make your lava lamp looks really cool. Take your light and your box with a small hole cut in the top and place your bottle on top of it.  What you do is turn off any other lights and drop another Alka Seltzer inside. you see the same reaction happening again. But this time it looks really cool . What's great about this is you can use the same bottle again and again.  All you have to do is break up another Alka Seltzer and put it through the neck.
