Lava and plastic don’t mix, or do they!

Lava and plastic, they don’t mix. Lava melts plastic. Well, how did they make lava lamps. They should of used plastic before putting it in mettle after(which still melts). You know, I found out how they’ve done it. It’s not real lava!

Edward craven walker made the lava lamps out of something else. Water oil and tablets. Oh, you’ll also need food colouring. Back than they didn’t call them lava lamps though. They called them Astro Lamps. He died when he was at war with cancer in the 1990’s.

Wanna know how to make one? Here it is: 1. Fill 1/4 of a plastic bottle with water. 2. Add a few drops of food colouring of your choice. 3. Tilt the bottle to the side and pour in some corn oil. 4. Set the bottle upright and let it set for 10 to 15 minutes. 5. Add two alka-seltzer tablets and you’ll have a fabulous, amazing, astonishing, stunning…….. LAVA LAMP.

This is hard, but not the hardest. We had to make a poster. This one is mine. imageI’m sure it’s an A3 page.

We needed all the info so this is the website I used. This website gave me heaps of information that I needed to use.image


On the day I had to stand for two hours. 48 or 49 people came to my table and all of them said mine was interesting loved it. This is the explanation:

If your scared, don’t worry. It’s not real lava. Its chemicals trying to mix. It makes bubbles float up making the effect of lava. The water has a higher density (the degree of compactness of a substance) then the oil, so as the water sinks, the oil sits on top. Cause of their densities, they’ll never mix.
The tablets will get stuck in the water and dissolve. This will generate carbon dioxide bubbles that float to the top. The food colouring makes everything visible to the eye. If we didn’t use food colouring, we wouldn’t see the bubbles float up so it will be a useless lava lamp.

Here is a video I used. img_2667. That’s the end of my speech. Good day.
