Suction is when something is being pulled towards something else so strongly that it sticks to it. This can happen when you suck on straw and the liquid gets pulled up through the straw and into your mouth. It's like a magical power that you can use to get things from one place to another without touching them. Imagine if you had a special toy that could suck up other toys and bring them closer to you. That's what suction is like! And it's not just a power for toys or humans - lots of animals use suction in their everyday lives to catch food or move around. So next time you see a vacuum cleaner or feel a straw in your mouth, remember that it's all thanks to the wonder of suction!
