Rainbow has long been considered a symbol of joy and optimism. After all, what could be more joyful than seeing a bright multi-colored arc in the sky in the middle of the rain. For adults, this spectacle causes a smile, and for children, a real delight. However, sometimes you really, really want to see a rainbow, but it doesn’t rain and it doesn’t rain, or, on the contrary, it rains without stopping, without missing a single ray of sunshine.
It is for such cases that we have prepared several ways to make a rainbow yourself at home or in the yard.
Making a rainbow with a hose
This method is perhaps the most difficult and troublesome, but the rainbow turns out exactly like a real one. Adults probably know how to make a rainbow in this way, but for children it seems like real magic.
This experiment should be done outside on a sunny day. Attach a special spray nozzle to the hose anddirect the jet upwards. The sun's rays will be refracted in small droplets, just like when it rains, and you will see a rainbow.
If there is no special nozzle, you can pinch the hose with your finger so that the water does not flow in a massive stream, but in many small sprays. The same experiment can be done on a smaller scale, outdoors or even indoors, using an ordinary plant sprayer instead of a hose.
Rainbow via CD
How to make a rainbow with an old cd-disk, many children know themselves. Well, if they don’t know, it’s time to show them this simple trick. To do this, you only need a disk and the sun's rays, well, or a flashlight. By the way, such a rainbow can be made even in the dark.
This effect can also be used in a photo shoot to take unusual bright photos, for example, sending rainbow highlights on or next to the face of the model.
You can make a garland out of pieces of old CDs and hang it on the window so that the rainbow looks into the room more often.
How to make a rainbow with a mirror
For this experiment you will need a transparent bowl of water, a small mirror and a flashlight. If you take a sheet of white paper, the rainbow will be seen more clearly. Position the mirror in the water so that it is submerged and at an angle. Now position the bowl so that the sun's rays fall on the mirror, or shine a flashlight. Place a sheet of paper in front of the bowl. The light reflected from the mirror will be refracted in the water,and you will see beautiful rainbow highlights on the sheet.
This is how you can make a homemade rainbow even on the most cloudy day.
And finally, we invite you and your child to watch an interesting and understandable video about how a rainbow appears in the sky if the sunlight is white and the water drops are transparent.
