Bubbles are one of the most fun things to play with…but what colour are they?
Transparent? Clear? See-through?
Did you know you can see all the colours of the rainbow in bubbles?
How to make rainbow bubbles
An empty clear bottle
Washing up liquid
Water
A sink
An overcast day (works best)I
Fill the bottle about three-quarters full with water
Add a squirt (scientific measuring there) of washing up liquid
Quickly tip the bottle and pour the water out fast.
You will find that the bottle is left full of bubbles.
These will look clear and normal, to begin with, but place the bottle on a windowsill and wait and watch over the next 30 seconds.
You will find that the bubbles will start to show signs of colour that will get stronger and stronger and that each bubble will look like it has been coloured like a rainbow!
Why can you see a rainbow in bubbles?
Visible Light from the sun is known as white light. It contains a range of colours, all with different wavelengths that, when together, form white light.
The colours of the rainbow are:
Richard Of York Gave Battle In Vain
Red, Orange, Yellow, Green, Blue, Indigo and violet
When white light from the sun shines through the film of the bubbles, the light is reflected and dispersed, splitting white light into its different wavelengths, revealing all the colours of the rainbow!

Wow! This is so cool! We’ll be doing this for sure! (and I’ve never hear the Richard of York phrase! We say Roy G. Biv, but quite honestly, when I was a kid, I used to get mixed up and say Roy B. Giv so it wasn’t a sure-fire way to remember the order for me lol)
Very fun and yet simple (doable) idea! Thanks for sharing! I’ll have to try this with my kids.

So easy as well! Just minutes and really effective.
Woah! I’m really loving the temmtate/lhepe of this site. It’s simple, yet effective. A lot of times it’s tough to get that “perfect balance” between usability and visual appeal. I must say you’ve done a awesome job with this. Additionally, the blog loads extremely quick for me on Safari. Outstanding Blog!
