Answer:
The syrup drop spreads in water without stirring because particles of syrup separate water molecules and bump into it and dissolve.
Explanation:
This is called diffusion. If you just leave the drop of syrup in the beaker for a while, it will eventually spread out around the beaker and all of the water will become sweet.
For example:
This is just like a restaurant, there is non-smoking half of the restaurant and there is a smoking half. The smoke will eventually spread out front he smoking corner to the non-smoking corner.
Another example:
If you pee in the pool, the pee will eventually spread out through the pool.
