Convection current animation
Watch a convection current drawn step by step: a pot of water on a flame, warm water rising up the middle, and cooler water sinking down the sides in two loops. A hand-drawn whiteboard animation made from one illustration.

DownloadThe prompt behind the picture
A side-view cutaway of a single clear glass pot of water sitting on a small stove flame. Inside the water, curved arrows show the convection current: warm red arrows rise straight up through the middle of the pot from the heated bottom, turn outwards along the top surface, then blue arrows sink down along both side walls and turn back inwards along the bottom, forming two closed loops, one on the left half and one on the right half. Only the pot, the water, the flame and the arrows; nothing else in the picture. Plain background with lots of empty space, 4:3. Coloured pencil and watercolour marker, clean black ink outlines, warm off-white paper, no text.The picture came from an image model; any finished illustration works the same way, including one you drew. Use the prompt as a starting point for your own topic.
How this clip was made
The picture above was made with an image model from the prompt above; WhiteboardAnimation.ai then drew it, stroke by stroke, as the clip at the top of this page.

Notes from making it
The narration was checked against NOAA’s JetStream page on heat transfer, which describes convection as heat moving through a fluid, with cooler, denser fluid replacing the warm fluid that rises, as in a boiling liquid.
Convection current, step by step
A script to read over it, timed to the drawing: the lines go down first and the colour arrives on the last beat.
- 0:00Line artConvection is how heat moves through a liquid or a gas, like water or air.
- 0:05Here is a pot of water sitting on a flame. The flame heats the water at the bottom.
- 0:10The warm water becomes lighter, so it rises up through the middle of the pot.
- 0:15At the top, the water spreads out to the sides and starts to cool.
- 0:21ColourCooler water is heavier, so it moves down along the sides to take the place of the rising water.
- 0:26Then it is heated again and rises. This loop that keeps going round is called a convection current.
Where this convection current animation fits
Use it in a physics or science lesson on heat, before a demo with food colouring in warm water, or as a short clip in a science video for kids. The same process turns your own diagram into a clip.
