气球的3种简单科学实验

3 Simple Science Experiments - Balloons

今天我将向你展示三大使用气球的实验
Today I’m gonna show you 3 great experiments using balloons.
首先
For the first,
我们将吹起来一个气球并在尾部打个结
we are gonna inflate balloon and tie it off.
然后 拿一个像这样的图钉
Next, take a pin like this,
把它放在桌面上
and place it on the table.
然后拿起你的气球
Then take your balloon
看看当你把气球放在图钉上时会发生什么
and see what happens when you put on the pin.
正如所预料的 气球立马爆炸了
As expected, it pops straight away.
接下来我们将会拿一把图钉
Next we are gonna take a whole handful of pins,
并像这样将它们放在桌面上
and lay them out flat like this.
然后再拿一个气球并重复上述操作
Then take another balloon and try doing the same thing again.
这一次就算你使劲压气球它也不会爆炸
This time you can push the balloon down onto the pins and it won’t burst.
这是因为压力被分散到了许多图钉上
This is because the pressure is now distributed over lots of pins,
而在各个图钉上的压力特别小不会使得气球爆炸
and the amount of pressure on each pin is too small to burst the balloon.
你甚至可以用一块砖去挤压气球
I even found you can bounce a house-brick on it
但要小心别压得太用力了
But do be careful not to push down too hard.
下一个实验
For the next experiment,
我们会拿一些白醋
we are gonna take some white vinegar,
并将它倒入塑料瓶中 像这样
and pour it into a plastic bottle, like this.
然后拿来一个气球和漏斗
Then take a balloon and a funnel,
然后将气球套在漏斗底部
and stretch the balloon over the end of funnel.
接下来我们需要一些小苏打
Next we need some baking soda,
向漏斗中放入两勺小苏打使之进入气球
and we are gonna put two table spoons down the funnel into the balloon.
当你弄好了 把气球从漏斗上拿下来
When you’re done, take the balloon off the funnel
并把气球套在瓶口上 像这样
and stretch it over the top of bottle, like this.
然后拿起气球让小苏打进入到瓶子中
Then lift the balloon up to empty the baking soda into the bottle.
它们立马发生了反应
This starts an instant reaction,
释放出的二氧化碳使气球膨胀起来
which produces carbon dioxide and inflates the balloon.
你可能需要抓着气球尾部以免它飞走了
You may need to hold the balloon onto the bottle to stop it flying off.
挺酷的 不是吗?
Pretty cool, ha?
最后一个实验
For the final experiment,
我们将取出一个蜡烛并点燃它
we are gonna take a candle and light it up.
然后拿起一个吹好的气球
Then inflate another balloon
把它放到火焰上看看会发生什么
and see what happens when you hold over the flame.
(嘭!)
(Boom!)
果然 气球立马爆炸了并吹灭了蜡烛
As expected, it pops straight away and actually blows up the candle.
接下来 再拿一个气球
Next, take another balloon
但这一次我们会像这样把气球中装满水
and this time we gonna fill it with water like this.
当你弄好了记得打个结
Tie a knot when you’re done.
拿起这个气球试试再把它放到蜡烛上方
Then take the balloon and try holding it above the candle again.
你可以看见这一次气球没有爆炸
You can see this time it doesn’t pop,
并且你还可以直接把气球放入火焰中
and you can actually hold the balloon right down into the flame.
气球中的水使得气球保持着低温
The water inside the balloon keeps it cool,
所以气球本身其实并未被火焰影响
so the balloon itself isn’t actually affected by the flame.
只是表面被烧黑了
All the happens is the balloon gets black.
是不是也很酷啊?
Pretty cool, ha?
