Wacky Water!

Try this experiment and then tell us what you discover!
 

What You Need:

  • A pitcher
  • Water
  • Food coloring
  • A glass
  • Newspaper
  • About 2 feet of string

Tip: Do this experiment over some newspaper. It can get a little messy!

Question: How can you pour water into a glass two feet away?

1) First, spread out some newspaper and put the glass on it .

2) Then, fill a pitcher half way with water and add a few drops of food coloring .

3) Soak the string in water .

4) Then, tie one end of the string to the handle of the pitcher. Let the other end of the string hang into the glass .

5) Stretch the string tightly across the top of the pitcher, while holding the other end of the string against the side of the glass..

6) Now, slowly pour the water along the string. Keep trying until you find the right angle for the water to run down the string.

7) Be amazed how the water runs along the string and doesn’t pour out onto the newspaper!

A Scientific Explanation:
There are three forces at work in this experiment: gravity, adhesion, and cohesion. Gravity pulls the water down toward Earth. Adhesion attracts water to other objects. Cohesion attracts water molecules to other water molecules. In this experiment adhesion attracts the water to the string and cohesion keeps the water flowing in a steady stream .

EXTRA! EXTRA!
Experiment with different distances. How far away can you get and still get the water to flow down the string?


I learned that it goes very slow going down the string. I thought
it would go very fast!

I did this experiment with my Dad and we discovered that
we couldn't get the water to go down the string unless we worked together to keep the string very straight.  One person had to hold each end while my Dad poured the water.  Then it worked!

IT WAS GREAT!!!

I learned that it was very cool!

It was great! At the end the newspaper was even not messy!!

I poured water on the string and it only went into the pitcher and I thought that was amazing

What happens is that the water runs along the string.

I tried it! It was so fun!

I discovered that I did it wrong!!!! I’ll try again.

Great Experiment!! I discovered that you can pour water really far. I poured down a string that was 12 feet long.

The water didn't spill. Instead I think it used electricity to hang onto the string. For example positives and negatives are in your hair so when you rub a balloon against it the balloon then sticks to the wall.

It does not drop off the string!
