Take a glass tumbler, fill it with water, put 4 raisins in it and keep the set up undisturbed for one day and observe it the next day and write your observations.
When a glass tumbler is filled with water and four raisins are added to it, the raisins will initially sink to the bottom of the tumbler due to their higher density compared to water. However, over time, the raisins will start to float to the top of the water in the tumbler. This is due to the process of convection, where the warmer water near the bottom of the tumbler rises to the top, carrying the raisins along with it. As the warmer water reaches the top, it cools down and sinks back to the bottom, creating a circular motion in the water called a convection current. This process repeats, causing the raisins to continually float to the top and sink back to the bottom of the tumbler, creating a mesmerizing visual effect. After a day, the raisins will have completed several cycles of floating and sinking, and will appear to be dancing or bouncing up and down in the water.
