Skittles Science Project (Candy)
What do you do when there is an oversupply of candies in the house, like the day after Halloween? (yeah, right.) Candy science experiment, of course! This experiment is really spectacular to watch, but the science behind is pretty complicated… actually, I haven’t found a definitive scientific explanation agreed by all authoritative scientists yet. But…
Traveling Water Experiment
Have you seen traveling water, i.e. water traveling from one cup to another without being close together or one directly above the other. It can be easily done with the help of a string! This traveling water experiment has demonstrated two important properties of water. Cohesion: Water molecules are attracted to one another and so they…
How Many Drops of Water Can Fit on a Penny Surface Tension Experiment
Why Water molecules attract each other and tend to stick together. This cohesion property results in surface tension. Because water molecules at the surface of the water puddle attract more to one other than they do to the air molecules above them, they cling together and form a dome shape on the coin. Surface tension prevents…
Toothpick Star Trick Science Experiment For Kids
Here is a super fun toothpick trick: turn broken toothpicks into a star! Video: The second part of the video has been sped up 4x times. So don’t be discouraged if your star doesn’t expand as fast as mine. Notes Toothpicks are made of dry wood. When dry wood absorbs water, the bent wood fibres…
Refraction of Light in Water Experiment (Video)
Notes Do the experiment again using different distances between the glass and the graphics. Try glasses and jars of different shapes. Try using different liquids such as oil, juice, etc. Why Have you noticed that things look a little funny when you see them through a glass of water? Some of the aberrations are caused…
How To Make A Rainbow – Simple Science Experiments
How Are Rainbows Formed? Sunlight or white light is a mixture of all the rainbow colors. The different rainbow colors are essentially mixed together to result in a white color. You may wonder why when you mix all the different colors of paint together result in black instead of light. That is because light mixing…
Why Is The Sky Blue? Simple Science (Video)
The Blue Sky On a clear day, you can see that the color of the sky is blue even though sun light does not seem to contain any color. So why is the sky blue if sunlight is colorless? Refraction Of Light The “colorless” light from the sun is actually white light. It is made up…
