I'm setting up for a science experiment, a spicy one using pepper and dish soap.

我正在準備一個科學實驗，一個會有點「辣」的實驗，會用到胡椒和洗碗精。

Have you ever seen the pepper experiment?

I just need to spice things up by adding some pepper.

我只需要加一點胡椒來「提味」。

You see that the pepper is sitting on top.

That's because the water is made up of lots of little molecules that sit closely together.

這是因為水是由很多小分子緊密地結合在一起組成的。

Things that are lighter sit on top and things that are heavier go through.

比較輕的東西會浮在上面，比較重東西就會沉下去。

And because the pepper is so light, it sits on top.

因為胡椒粉很輕，所以會浮在水面上。

Let's see what happens if I dip my finger into this dish soap and then drip it into the peppery water.

那我們來試試看，如果我把手指沾一點洗碗精，然後滴到胡椒水裡會發生什麼事？

The pepper spread away from the dish soap like magic.

胡椒粉就像變魔術一樣散開了。

What happens is the dish soap breaks the surface tension, which makes the water molecules spread apart and takes the pepper with it.

這是因為洗碗精打破了表面張力，讓水分子散開，也把胡椒粉帶走了。

I made the pepper move without even touching it.

我讓胡椒粉移動了，而且我根本沒碰到它。

If I can make the pepper move, maybe I can make something else move through the water.

如果我能讓胡椒粉移動，也許我能讓別的東西在水裡移動。

For this experiment, you'll need leaves, a plastic spoon, dishwashing liquid, pepper, food colouring, a large deep tray or container, water, and

這次實驗，你需要葉子、塑膠湯匙、洗碗精、胡椒粉、食用色素、一個大型深盤或容器、水，還有

I'm thinking the drip of dish soap moved the pepper across the water.

我猜是那一滴洗碗精把胡椒粉移到水面上的。

Maybe I can find something else that moves other things through the water like a boat.

也許我可以找些別的東西，像小船一樣在水上移動東西。

In science, we like to test lots of things together to see how they work together.

在科學裡，我們喜歡把很多東西一起測試，看看它們是怎麼互動的。

That's an important part of the scientific process.

Anyway, first I've got these containers of water for our boat to zoom through.

總之，我先準備了這些水容器，讓我們的船可以快速通過。

I'll just finish filling this one up and then everything is ready to go.

我先把這個裝滿，然後一切就準備好了。

It's time for science, and scientifically, maybe we'll make a discovery.

是時候來點科學了，從科學的角度來看，也許我們會有些發現。

First, I'm going to use a leaf as the boat.

首先，我會用一片葉子當小船。

Now I need to dip the leaf stem into the pepper.

現在我需要把葉子的莖沾到胡椒裡。

A little bit of water on the stem so the pepper will stick.

在莖上沾一點點水，這樣胡椒就會黏住了。

Oh, can you see the pepper sticking to the leaf stem?

喔，你看得到胡椒黏在葉子的莖上嗎？

The leaf isn't zooming through the water.

Well, the leaf and the pepper did not work.

Okay, now I'm gon dip the end of this spoon into the food colouring.

好的，現在我要把湯匙的這一端沾到食用色素裡。

Well, look, it certainly looks interesting with all the food colouring swirling and whirling through the water.

嗯，你看，食用色素在水裡這樣旋轉、舞動，看起來確實很有趣。

Oh, it's too heavy to float, so it doesn't make a very good boat.

喔，它太重了，沒辦法浮起來，所以做不成什麼好用的船。
