Hydrophobe

Hello, kiddo! Today I am going to tell you about something called hydrophobe.

Have you ever noticed that when you pour water on some things, the water just slides off? Like a duck's feathers or a leaf? That's because these materials are hydrophobic, which means "water-fearing".

You see, water molecules have a special property called polarity. This means that some parts of the molecule are positively charged, while others are negatively charged. When water comes in contact with a hydrophobic material, the charges repel each other, just like when you try to push two magnets together with the same poles facing each other. This makes the water bead up and roll off the material.

Of course, not all materials are hydrophobic. Some are hydrophilic, which means "water-loving". These materials attract water molecules, and when water is poured on them, it spreads out and wets the surface.

So, remember, hydrophobic means "water-fearing" and hydrophilic means "water-loving". And now you know why some things get wet and others don't!
