We're working on designing rafts for Juniper!

我們正在為瞻博網絡設計木筏！

We're all going to the lake together, but Juniper is too small to swim, and Squeaks can't find the boat he was going to lend her.

我們要一起去湖邊，但是裘妮波太小了，不會游泳，而斯奎克斯也找不到他要借給她的船。

We talked about how to solve this problem, and we decided we could make her a raft!

我們討論瞭如何解決這個問題，決定為她製作一個木筏！

Juniper, Squeaks, and Sam each drew a picture, or design, for a raft that Juniper might be able to use on the lake.

瞻博網絡、吱吱和山姆各自畫了一幅畫，或者說設計了一個瞻博網絡可以在湖上使用的木筏。

But we still have to decide which design to use.

但我們仍需決定採用哪種設計。

These look awesome, and it's something engineers do, too!

這些看起來棒極了，工程師們也會這麼做！

They look at their drawings to build a special model of their design, called a prototype.

他們根據自己繪製的圖紙，為自己的設計製作一個特殊的模型，稱為原型。

Then, engineers test their prototypes to see how well their design solves the problem.

然後，工程師會對原型進行測試，以瞭解他們的設計在多大程度上解決了問題。

那麼，讓我們來測試一下我們的原型吧！

Remember, our raft needs to do three things.

請記住，我們的木筏需要做三件事。

讓我們看看她的設計有多出色！

Juniper made a raft out of aluminum foil.

The raft floated when we put it in the water, and the pipe cleaners we used for testing fit inside its shape, which kind of looks like a bowl.

當我們把木筏放入水中時，它浮了起來，而且我們用來測試的清管器也可以放入木筏的形狀中，看起來有點像一個碗。

And splashing in the water is part of the fun!

But I don't think I'd feel very safe in that raft.

但我不認為我在木筏上會感到很安全。

He made his raft out of craft sticks, which we know float in water.

他用工藝棒製作了木筏，我們知道工藝棒可以漂浮在水面上。

Its shape is different from the foil raft.

This raft is flat, and it has a handle in the middle for Juniper to hold onto.

這個木筏是扁平的，中間有一個把手，供瞻博網絡抓握。

I don't want to get too wet, and I'm not sure how well I can hold onto that handle.

我可不想弄得太溼，而且我也不確定自己能不能抓住那個把手。

Now, Sam made his model from cardboard and corks.

現在，山姆用紙板和軟木塞製作了他的模型。

It floats really well on the water at first.

一開始，它在水面上漂浮得非常好。

It had a wide, flat shape, and had plenty of room for Juniper.

它的形狀寬闊平坦，為杜松提供了充足的空間。

但看看一段時間後會發生什麼。

The cardboard gets wet and starts to sag and fall apart.

And I want Juniper to be able to play all day with us.

我希望瞻博網絡能和我們一起玩一整天。

But how do we know which one Juniper should use?

但是，我們如何知道瞻博網絡應該使用哪一種呢？

They would try again to find a solution to the problem.

他們會再次嘗試找到解決問題的辦法。

True, but engineers rarely expect their designs to be just right the first time.

沒錯，但工程師很少指望他們的設計第一次就能達到完美的效果。

That's why we test and compare our ideas, so we can learn from them and make improvements.

這就是為什麼我們要測試和比較我們的想法，以便從中吸取經驗教訓並加以改進。

It's not about getting it right the first time.

It's about learning and making our designs better.

這是為了學習，讓我們的設計變得更好。

What did we learn when we tested the rafts?

我們在測試木筏時學到了什麼？

We can use that to make our next designs better.

我們可以利用這一點，讓我們的下一個設計變得更好。

Oh, Squeaks thinks we should use craft sticks instead of cardboard, because his raft didn't get soggy.

哦，Squeaks 認為我們應該用工藝棒代替紙板，因為他的木筏沒有變溼。

But we should use enough of them so that the raft has the same shape as mine, wide and flat.

但我們應該使用足夠多的木筏，這樣木筏的形狀才會和我的一樣，又寬又平。

That way, there's plenty of room for Juniper.

這樣，瞻博網絡就有足夠的空間。

And we could still use the corks like I did in my design.

我們還可以像我在設計中那樣使用瓶塞。

That way Juniper will be nice and high above the water.

這樣，瞻博網絡就會很好地高出水面。

What if we added sides to the raft, like in my design?

如果像我的設計一樣，在木筏上加個邊呢？

That will help keep me from falling off the raft, even if the water gets rough.

這樣，即使水流洶湧，我也不會掉下木筏。

You're using everything we learned to improve our design.

你們利用我們學到的一切來改進我們的設計。

Let's put all of these ideas together to make a new design.

讓我們把這些想法結合起來，做出一個新的設計。

Operation Save Juniper's Vacation has reached its final phase.

拯救瞻博網絡假期行動已進入最後階段。

好了，我們的木筏漂起來了嗎？

And will it keep Juniper safe, even if there end up being waves in the lake?

即使湖中最終會出現波浪，它能保證瞻博網絡的安全嗎？

We've worked together, just like engineers do, to come up with a design that solves a problem.

我們就像工程師一樣共同努力，設計出解決問題的方案。

我們即將迎來一個激動人心的假期。

I have some fascinating new results I wanted to share with you in all my studies of buoyancy and fluid dynamics.

在我對浮力和流體動力學的所有研究中，我有一些引人入勝的新成果想與大家分享。

We've been doing some studies of our own.

And it was just going to be for a couple of minutes, but then all the experiments were so fascinating that I got a bit carried away.

本來只想看幾分鐘，但後來所有的實驗都太吸引人了，我有點忘乎所以。

Ugh, you mean we did all that work for nothing?

唉，你是說我們白忙活了一場？

我很享受像工程師一樣思考的過程！

In fact, I might still use the design we made together.

事實上，我可能還會用我們一起設計的那款。
