Plastic Milk by sunshiine

牛奶塑料

I was trying to find a recipe I could use to produce a chemical reaction for the Mad Scientist contest and the chemical reaction contest. I came across this one and thought is was interesting. For this tutorial I will be making Plastic milk.
我打算弄一份配方，用做疯狂科学家比赛和化学反应比赛中的配方。偶然之下发现了这个配方，还比较有趣，于是在这个教程当中，我会做一个牛奶塑料。

Step 1: Recipe

一、配方

Recipe ingredients:
2 Cups Milk
2 Tablespoons white vinegar
配方成分：
两杯牛奶
两茶匙白醋

This recipe came from here: http://www.youtube.com/watch?v=pIvAl4lu1uA.
这份配方从这个视频当中可以看到。

It is very helpful to view this video so you can see the process of making plastic milk.
这个视频很有帮助，你能从中看到制作牛奶塑料的过程。

It is a quick and easy project.
这是个简单快速的作品。

Step 2: Utensils

二、容器

Utensils needed:
Liquid measuring cup
Measuring spoons
Coffee filters to absorb the liquid
Fine weave strainer
Spoon
Plate
Pan
Cookie cutters
Skewer not shown
Wax paper not shown, line the plate with wax paper.
需要的器皿：
液体量杯
量匙
咖啡滤纸，用来吸收液体
密纹滤网
茶匙
盘子
平底锅
曲奇饼切模
没在图上显示的竹签
没在图上显示的蜡纸，用来衬着盘子用的

Step 3: Measure/ Heat

三、测量/加热

Measure:
测量：
Measure 2 cups milk and set aside.
Measure 2 Tablespoons white vinegar and put it into a small glass reserving until later.
Line the strainer with 2-3 coffee filters or paper towels.
Line the plate with wax paper.
- 量出两杯牛奶，放置待用。
- 量出两茶匙白醋，放在个小杯子里，保留待用。
- 在滤网上铺上两到三层咖啡滤纸，或者用纸巾代替也行。
- 在盘子上衬上蜡纸。

Pour the milk into the pan and heat on stove. Do not boil! Heat until almost too hot to touch but not boiling
将牛奶倒入平底锅，打开煤气炉。不要沸腾！加热到差不多粘底的温度，但不要沸腾。
Add vinegar.
Stir gently.
Allow it to separate into globs.
Stir again.
- 加入白醋
- 略略搅拌
- 让它分离成块
- 继续搅拌

Step 4: Strain

四、滤干

Remove from the stove:
** 从煤气灶上取下来：
Place strainer in sink.
Pour Contents into the lined strainer.
Allow to drain a couple of minutes.
Carefully pull up the filter and gently press with your fingers to remove liquid from ball.
You might need to place it in another doubled coffee liner and squeeze again to remove excess moisture.
It should begin to form a paste.
Let it set 5 minutes.
- 在水槽上放上滤网。
- 将做好的东西倒入铺好的滤网上。
- 让其滴干几分钟。
- 小心从滤网上拉起来，用手指轻轻按下，榨干球球里面的液体。
- 可能需要放上另一片双层咖啡滤纸，再次挤压，去除多余水分。
- 可以开始制成膏状物。
- 让其静置5分钟。

Step 5: Molding

五、倒模

Method:
方法：
Gently roll the plastic in a tight ball.
Gently press flat to form shapes.
This part is tricky you need to work with it and try to keep it together nicely.
You accomplish this by pressing down and pulling toward the center with your hand.
Using the cookie cutters make the shapes.
Form a couple of balls if you desire.
Using the skewer poke holes where you want if you are going to make jewelry.
- 轻轻地将塑料揉成紧密的球状。
- 将其轻轻按扁，开始塑形。
- 你需要有技巧操作，让东西美观地结合在一起。
- 在手里用挤压和和向中心推压的方式完成。
- 用曲奇饼切模造型。
- 或是随自己性子做几个小球球。
- 如果要做首饰珠宝的话，在需要的地方用钎条戳几个洞洞。

Step 6: Place Shapes On Plate

六、在盘子上放模型

Place the shapes on the plate lined with wax paper:
**在铺上蜡纸的盘子上放上模型：
Place the shapes on a plate.
Set in a safe warm area away from children and pets.
Allow to dry
Turn over after a few hours to allow the back side to dry.
- 在盘子上放上模型。
- 原理儿童、宠物，放在个安全温暖区域（译者注：这就是安全意识，要不然小猫闻到香味会过来啃两口的……）。
- 让其干燥。
- 在几个小时后翻身，让背面干燥。（译者注：个人建议放在微波炉，开最低火量，或者放在暖气片上也可以。）

Please note: I made a ball because they mentioned it was rubbery and I thought I would see if it bounced. We will see.
补充：我做了个球球，因为视频中提到这是带弹性的。我打算看看这能否弹起来。来看看吧。

Step 7: Uses

七、用途

Uses:
用途：
Allow to completely dry before working more with it.
You can make shapes from the plastic clay.
Paint it when it is dry.
Write on it.
Make jewelry.
If you can mold a perfect circle it bounces.
Embellishments for many things.
Gift tags.
Dog Tags.
Key ring tag.
Picture frames?
Dolls.
Game pieces.
This list is very long.
- 在更多加工操作前，让其完全干透。
- 用这坨塑料粘土可以塑形。
- 干燥后涂色。
- 或者在上面写东西。
- 用作珠宝。
- 如果能塑形成完美球形，估计能弹起来。
- 修饰成很多东西
- 狗牌
- 钥匙扣
- 画框？
- 人偶
- 游戏道具块
- 总之一言难尽

I can't wait until the paint dries so I can create something that I will post here when it is done.
我等不及了，油漆未干呐，这样我能做一些在这里登出的作品了。

Step 8: Sunshiine's Final Thoughts

八、Sunchine的最后想法

This was a fun experiment. It would make a great craft project for the family.
这是个有趣的实验，能为家庭制作不错的手工作品。
What I did was turn milk into a solid through a chemical reaction known as a polymer molecule strand.
我做的是将牛奶通过一种聚合物化学反应变成固体。
The individual protein strands within the milk and the vinegar solidified making plastic.
原本牛奶中独立的蛋白质聚合化，醋则将其刚性化，变成塑料。

The plastic is based on a protein called casein - adding the acid causes it to unfold from its usual tangled form,and change into longer sections, which are the lumps that are removed to form the ball .
这塑料是由一种称为干酪素组成，加入酸就让它从原本杂乱无章形态解绑出来，变成长链形态，变成团状来塑成球状。
Casein-plastic used to be used to make shirt buttons.
干酪素塑料通常用于制作衬衫纽扣。
Some cheeses (like the processed cheese slices) are made in a very similar way, so can be genuinely called "plastic cheeses".
有些奶酪（例如处理过的奶酪片）的制作方法很近似，所以这能称为”塑胶奶酪“。
I Painted the shapes thinking I would glue them on boxes for embellishments or make jewelry. I am very happy with the results.
我将模型上色，打算将它们粘在盒子上用作装饰，或者用来制作首饰。有这个结果我很高兴。

Thanks you for stopping by and please check back soon as I am working on some interesting things to share.
