What kid doesn’t love rainbows? I know mine do and so I have decided to come up with a list of rainbow related experiments and crafts we can do!

 

Rainbow Melted Crayon (picture by 52 Kitchen Adventures)

10Rainbow Melted Crayon Art

I am yet to try this one myself but it looks like it would be a lot of fun. My children are scared of the hair dryer so will have to wait a bit. All you need is some cardboard, a hair dryer and crayons.

  1. Glue crayons on canvas/cardboard
  2. Use blow dryer to melt crayons
  3. Have an awesome piece of artwork.

7Rainbows by Sunshine

You’ll need:

  • sunlight
  • White paper
  • clear glass of water

Instructions

  1. Take the glass of water and paper to a part of the room with sunlight (near a window is good).
  2. 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 colours on your sheet of paper.
  3. Try holding the glass of water at different heights and angles to see if it has a different effect.

6Sparkling Fizzy Rainbows

You’ll need

  • Colored Baking Soda Dough (click here for instructions)
  • vinegar and cups to put it in
  • pipettes (optional)
  • pan to contain the rainbow and the sparkly fizzy eruptions

Instructions

  • Arrange your baking soda dough into a pan in the colours of a rainbow
  • Use pipettes to add vinegar!  Ask your children what they think will happen when you mix the vinegar and the colored baking soda dough.  Ask them why!  Then let them get to work!!  They will see the vinegar and baking soda react to release carbon dioxide. Carbon dioxide is a gas and makes bubbles wherever the other two reactants touch!

5Rainbow Jar

You’ll need:

  • A tall, see-through container (I used a clean mason jar.)

  • Dish soap (either blue like Dawn or green like Palmolive)
  • Olive oil
  • Rubbing alcohol

Rainbow Bubbles (by Science Sparks)

4Playdough Bubbles

You’ll need:

  • An empty clear bottle
  • Washing up liquid
  • Water
  • A sink
  • An overcast day (works best)
  1. Fill the bottle about three quarters full with water
  2. Add a squirt (scientific measuring there!) of washing up liquid
  3. Quickly tip the bottle and pour the water out fast.
  4. You will find that the bottle is left full of bubbles.
  5. 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.
  6. 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!
