6 . Blowing Up Balloons with CO₂
Chemical reactions (化学反应) make for some great experiments. You can make use of the CO₂(carbon dioxide) given off by a baking soda (小苏打) and lemon juice reaction to blow up your balloon!
What you’ll need:
●Balloon ●About 40ml of water ●Soft drink bottle
●Juice from a lemon ●I teaspoon of baking soda
Instructions:
●Before you begin, make sure that you pull the balloon long to make it as easy as possible to blow up.
●Put the 40ml of water into the soft drink bottle.
●Add the baking soda and mix it with water.
●Put the lemon juice in and quickly put the balloon over the mouth of the bottle.
What’s happening?
If all goes well, then your balloon should inflate! Adding the lemon juice to the baking soda creates a chemical reaction and produces CO₂. The gas rises up and escapes (逸出) through the soft drink bottle. It doesn’t, however, escape the balloon, pushing it outwards and blowing it up.
1. Which of the following do you need for the experiment?A.Two cups. | B.Apple juice. |
C.250 ml water. | D.A teaspoon of baking soda. |
A.Heat the water. | B.Drink some juice. |

In 1895, Elias Howe was struggling with the needle (针) design. One night, he had a dream that some people on an unknown island caught him and were preparing to turn him into a meal. They were dancing around waving their spears (矛) in the air, and then he saw it. The spears had holes at the tip. It helped him solve his problem.
Einstein’s theory of relativity
In his dream , Albert Einstein was talking to a farmer who was telling him about the fenced (被围住的) cows. However, the farmer saw something different from him. When waking up, he realized that a similar event could be different from a different point of view. Through this, the theory of relativity slowly began to fall into place.

Yesterday by the famous band Beatles is one of the most covered songs in history . It all came to one of the band members, Paul McCartney, in a dream. One night in 1963 he suddenly woke up with a tune (曲调) in his head. He got up and started playing the notes until the song came into being.
The periodic table
While in his mid - thirties, Dmitri Mendeleev, a known Russian chemist, was struggling to place 56 known elements on a periodic table. Then one night in a dream, he saw a table where all aspects fell into place as called for. When he woke up, he wrote it down on a piece of paper.
