Mysterious Floating Egg & An Ocean In A Bottle



WATCH THE VIDEO BELOW AND TRY TO MAKE A FLOATING EGG & AN OCEAN WITH A BOTTLE! 

INTERESTING EXPERIMENT THAT CANNOT BE MISSED~!!


WHAT ABSORBS MORE HEAT?

When you're out in the sun on a hot summers day it pays to wear some light colored clothes, but why is that? Experiment with light, color, heat and some water to find out.

WHAT YOU'LL NEED:-

* 2 identical drinking glasses or jars
* Water
* Thermometer
* 2 elastic bands or some sellotape
* White paper
* Black paper

INSTRUCTIONS:

(1) Wrap the white paper around one of the glasses using an elastic band or sellotape to hold it on.
(2) Do the same with the black paper and the other glass.
(3) Fill the glasses with the exact same amount of water.
(4) Leave the glasses out in the sun for a couple of hours before returning to measure the temperature of the water in each.

WHAT'S ACTUALLY HAPPENING?

Dark surfaces such as the black paper absorb more light and heat than the lighter ones such as the white paper.
After measuring the temperatures of the water, the glass with the black paper around it should be hotter than the other.
Lighter surfaces reflect more light, that's why people where lighter colored clothes in the summer, it keeps them cooler

YOU ARE MY SUNSHINE
MY ONLY SUNSHINE
YOU MAKE ME HAPPY 
WHEN SKIES ARE GREY
YOU NEVER KNOW, DEAR
HOW MUCH I LOVE YOU
PLEASE DON'T TAKE MY SUNSHINE AWAY

MAKING A RAINBOW~!!

*~RAINBOW~*

HOW TO MAKE YOUR OWN RAINBOW:-

Learn how to make a rainbow with this fun science experiment for kids. Using just a few simple everyday items you can find out how rainbows work while enjoying an interactive, hands on activity that’s perfect for kids.


WHAT YOU'LL NEED:
  • A glass of water (about three quarters full)
  • White paper
  • A sunny day

    INSTRUCTIONS:
  • Take the glass of water and paper to a part of the room with sunlight (near a window is good).
  • Hold the glass of water (being careful not to spill it) above the paper and watch as sunlight passes through the glass of water, refracts (bends) and forms a rainbow of colors on your sheet of paper.
  • Try holding the glass of water at different heights and angles to see if it has a different effect.

WHAT'S ACTUALLY HAPPENING?

While you normally see a rainbow as an arc of color in the sky, they can also form in other situations. You may have seen a rainbow in a water fountain or in the mist of a waterfall and you can even make your own such as you did in this experiment.

Rainbows form in the sky when sunlight refracts (bends) as it passes through raindrops, it acts in the same way when it passes through your glass of water. The sunlight refracts, separating it into the colors red, orange, yellow, green, blue, indigo and violet
