Science - Lava Lamp Experience

Material: 

Vinegar, Sodium bicarbonate, Citric acid, Oil, Food Colouring, Water, empty Water bottle.

Method:

1.  Add colouring in 50 ml of water in a beaker.

2.  Pour the coloured water into an empty water bottle.

3.  Add vinegar and make the bottle half-filled.

4.  Add vegetable oil up to the bottleneck ( close to the top).

5. Add sodium bicarbonate and citric acid.

RESULT : 

I think my group and I did good compared to some of the other groups, but they did good as well. If I had the chance to do this experiment again, I’ll take that opportunity to do so.
