Description:

 

Soap is really good at washing germs off your hands as it breaks down the surface tension, meaning the oil on your hands (where the germs stick) is broken down and washed away.

Hi, I'm Nano girl, and I want to be a superhero.and this week the superpower that I'm trying to get is the power to fight bunnies like hot viruses For this, we're gonna need some soap, and this is gonna be our incredible weapon. But how do we know that it's actually working? I mean, we can't see viruses because it's... So how do we know if they're gone after we wash our hands? Luckily, I know an experiment that will show us how soap works. We need a few items from your Fortress of nourishment, oh thank y'all kitchen by the way just a name I made up for mine. 

And moving on, you will need a bowl of water, some liquid dish soap, a towel, and some pepper.

We know that we need to wash our hands with soap. What does the soap actually do to germs? 

Well, for this, sprinkle some pepper onto the surface of your bowl. Imagine that the pepper is basically tiny really germs but these are big enough that you can see. 

Now, put your finger into the water and pull it out. Oh who do we have germs all over my finger that is disgusting. 

Okay, now I'm going to show you the same experiment when I put a tiny drop of soap onto my finger. 

So we're gonna do the same thing and take a look. Look at that, the germs all moved away, and that's what happens when you wash your hands with soap. 

The soap particles change something called the surface tension which moves the viruses away from your hands and for some viruses it even makes them explode. 

Then you just wash them down the drain or down the sink by rinsing your hands in water, and the bunny viruses are destroyed. well,we're talking about cleaning our hands, and it's point time I gave mine another wash to the butchers our cleanliness that's the bathroom, by the way, another one of my cool names, you know it's where you clean, no never mind.
