Lava Lamps in Science

 There was great excitement in school this afternoon. We made lava lamps! We made these during science. We were learning about the density of oil and water. This experiment was to show the properties and characteristics of these materials, and to prove that oil is less dense than water. We went outside to test a lava lamp and it exploded! We got quite a fright when we heard the bang!

The lava lamps are so simple to make. Here's what  you do:

1. Fill a bottle to the half way mark with water.

2. Add vegetable oil.

3. Watch and take note of the reaction.

4. When it stops bubbling, add food colouring of your choice.

5. Again, record the reaction of the materials.

6. Lastly, add the alka seltzer tablets. (only add a quarter of a tablet at a time)

7. Sit back and watch a lava lamp take shape!

Oh the suspense!

What's going to happen next!

Tada!
