A rainbow is
caused by the collision of sunlight and certain atmospheric conditions. Light
enters a water droplet, slowing down and bending as it goes from air to denser
water. The light reflects off the inside of the droplet, separating into its
component wavelengths–or colors. When light exits the droplet, it makes
a rainbow.

Now that you know the science behind rainbows, now we need to figure out a way to remember all those colors! Allow me to introduce you to my friend, Roy G. Biv. He is not a real person, but his name is the acronym that helps us remember the colors of the rainbow, or in more precise science terms, the colors that make up the visible light portion of the electromagnetic spectrum! The colors are Red, Orange, Yellow, Green, Blue, Indigo, and Violet.

Have you seen this fun video by They Might Be Giants? It teaches you about ROY G BIV & the electromagnetic spectrum!

Rainbows have held incredibly special meaning to people, forever. In fact, the rainbow flag was created and became known as the gay or LGBTQ symbol for lesbian, gay, bisexual, transgender, and queer (LGBTQ) pride and LGBTQ social movements. Rainbow flags have also served as a symbol of peace.

But there are many myths and
folklores surrounding rainbows. Here are some of
the more common tales and beliefs about rainbows:

  • Biblical accounts establish
    the rainbow as a covenant, or promise, between God and every living
    creature, that the earth will never again be destroyed by flood.
  • In Greek
    mythology rainbows were thought to be a path between Earth
    and Heaven. The rainbow was called the “Bridge” in Norse mythology,
    connecting Asgard, the home of the gods with Midgard, the home of humans.

  • A pot of gold at the end of every rainbow that is guarded by a tricky leprechaun. The legend goes like this… Once upon a time, the Vikings lived in Ireland, looting, and plundering as they pleased, then burying their ill-gotten treasures all over the countryside. When they eventually departed from the Emerald Isle, they inadvertently left behind some of their booty, which the leprechauns found. Now, the leprechauns knew the Vikings had gotten their treasures through stealing, which was wrong. This bad behavior made the leprechauns mistrust all people, Viking or not. To ensure no humans could take what they now considered their gold, the leprechauns reburied it in pots deep underground all over the island. When rainbows appear, they always end at a spot where a leprechaun’s pot of gold is buried.

you ever wondered if there are different kinds of rainbows? There are 12
different types of rainbows. When you see the typical rainbow that forms after
a storm, you may think that is all there is to it. But in truth, there are all
sorts of rainbows—some rarer than others. Each type of rainbow is created under
different circumstances and falls either into primary or secondary types.

Have you ever heard of a Fogbow? A
fogbow is a type of rainbow that occurs when fog or a small cloud experience sunlight
passing through them. The droplets of moisture from the fog work to diffract
that light. This type of rainbow is usually found in places where the fog in
the air is thin. It can also form above any body of water. Typically, this
rainbow consists of blue, white, and red. Much of a fogbow rainbow is white,
with blue appearing on the inside and red appearing at both ends.

Have you ever heard of a moonbow? A lunar rainbow (aka “moonbow”) is an unusual sight. This event occurs on the moon during a lunar month. The moon must be almost fully lit up for this type of rainbow to form. When it does, it appears as a white arc. Lunar rainbows line the moon’s outer rim. They are dull in appearance because the light on the moon is not as bright as the light on earth.

Can we have more than one rainbow at a time? Yes, they are called multiple rainbows. One of the rarest forms is multiple, or double, rainbows. They occur when several rainbows form in the same place at the same time. It takes at least one primary rainbow to generate this sight, as well as several other secondary rainbows. There is always space in between each one.

Double Rainbow

This space is referred to as
Alexander’s Band. In around 200 AD, Alexander of Aphrodisius observed that,
during rain, the area between primary and secondary rainbows appears
considerably darker than the surrounding sky. The phenomenon occurs because the
refractive index of light means that light from raindrops in the region of the
sky between the two rainbows cannot reach the observer. When sunlight is
reflected in raindrops, a double reflection occurs. White light reflects off
the colors of the primary rainbow, creating secondary ones.

There are even twin rainbows! A
twinned rainbow is also a rare sight to see. Though they have one base in
common, two rainbows are formed, with one being primary and one being
secondary. The colors of both rainbows are seen in the same sequence. When two
rain showers occur, the size of the raindrops can lead to the formation of a
twinned rainbow. With different shaped and sized raindrops from each storm, one
rainbow becomes two. In an even rarer sight, a twinned rainbow can include the
formation of as many as three.

Can the shape of rainbows change, or are they always an arc? Rainbows can change shapes, some can even be a full circle. In most cases, rainbows are semicircular arcs. Yet on rare occasions, it is possible to spot a full circle rainbow. This type of rainbow typically occurs in high altitude areas. At lower altitudes, the position of the sun prevents a full circle from being formed. Anything obstructing the sun also makes it impossible for this type of rainbow to form. When it does, it may include both primary and secondary rainbows.

FUN Science: Make Your Own Buckyball!


If you’ve kicked around a soccer ball, you may have noticed the pattern on the ball’s surface. The ball is stitched together from 12 patches with five sides (pentagons) and 20 patches with six sides (hexagons).

About 20 years ago, chemists discovered that carbon can form into molecules with the same shape. This molecule is sometimes referred as the C60 molecule but is most commonly known for its nickname “the buckyball”.  The Buckyball, or C60 molecule was discovered by accident (in the lab) while trying to understand the chemistry between the stars in the Interstellar Medium ISM.  The discovery led to the Nobel Prize in chemistry in 1996.  

Each  Buckyball molecule is made up of 60 carbon atoms called a truncated icosahedron and belongs to a group of materials known as nano-materials. Nano-materials are created by scientists by manipulating individual atoms to build molecules of different shapes. Groups of these molecules form materials with particular characteristics, making them suitable for different jobs. For example, some nano-materials are already being used in makeup and sunscreens. 

The strong, hollow particles that make up the Buckyball may someday be used to carry medicine or even block the action of certain viruses.

Making your own Buckyball Molecule is simple with our cool molecule template! Get the template here

Here’s how you do it…

2. Cut out each cool molecule design & tape it together. It should resemble a soccer ball!

When assembled it will have 32 faces, of which 20 are regular hexagons and 12 are pentagons. We want to see how cool your buckyball turned out!

Send in your pictures of your cool Buckyball & they could end up published on our blog & facebook page! Email your pictures to! 


Parents Magazine Lists 5 Ways To Have FUN with Science!



How many times a day do you think kids ask “why”? Probably too many to actually keep count even if we tried!  Kids are naturally equipped with a curiosity of how things work. I guess you could say that they are researchers in their own rite. Wired like little sponges, children will absorb any information they come across. You don’t have to take your kids to a research facility or science lab for them to learn how cool science is, a few simple household items is all that’s needed to make science fun!  When it comes to science, its quite simple to entertain and fascinate the kids of all ages. For the September issue, Parents Magazine has listed 5 simple science experiments that are sure to impress by illustrating a few basic scientific principals.
