Today 3D and 3E completed our first Science Experiment! We made lava lamps. We used water, vegetable oil, food colouring and effervescent tablets. We discovered that when water and oil mix together they seperate. When we added the food colouring, it passed through the oil and into the oil. The tablet made the food colouring raise and fall throughout the bottle. The more tablets we put in, the more it looked like a lava lamp. It was awesome!!
