Lava lamp - Science

 Aim: Make your own Lava Lamp

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: 

In the science lab we made lava lamps.We made lava lamps using 50mls of water , food colouring ,vinegar ,vegetable oil ,sodium bicarbonate and citric acid.First we got a empty water bottle and then we got some water and put some food colouring in.After that we got vegetable oil and put it into the water.Then we got sodium bicarbonate and citric acid and put some into the water bottle. That's how we made our own lava lamp.We also reached the aim and made a lava lamp.
