On Friday we did a science experiment. we made a lava lamp out of berocca, vegetable oil, food colouring and water. Then we blew it up with more Berocca.
Method:
We put vegetable oil into a bottle. Then we added water to it. At that stage the water sunk to the bottom because oil is more dense than water. Then we added food colouring. It to like the water sunk to the bottom, but unlike the water it went in little bubbles. Next we added 2-3 berocca's. If you put a berocca into normal water it fizzes up and changes the colour and flavour of the water. The berocca's sunk through the oil without fizzing, when it hit the water and food colouring it created a lava lamp like appearance.
