Rainbow jar – #jamjarcreations

By Lyndsey Jenkins,

Over the last few weeks during lockdown, we’ve been getting crafty here at jamjar repurposing our used jam jars. 

We wanted to share our #jamjarcreations with you in case you have some jam jars hanging around the house.

The first activity is a great one to do with kids. Not only is it fun to do and easy to make, but it involves some counting and measuring so can definitely be classed as educational!

As the rainbow has become a symbol of support for people wanting to show solidarity with the NHS as the coronavirus pandemic has swept the country, it’s a timely and fitting jar to create at the moment and pop on your windowsill.

What you’ll need

  • A large jar – we used a used 600g peanut butter jar
  • Acrylic paints in rainbow colours
  • Long skewer or prodding utensil
  • At least 60 cotton wool balls
  • Water
  • Cup for measuring
  • Mixing pots or ramekins x 6
  • Measuring spoon

How to make your rainbow jar

  • Fill each ramekin with half a cup of water. You should have six pots/ramekins in total.
  • Starting with red, add 1tsp of red paint to your first ramekin and stir in the colour to the water.
  • Repeat this process with all of your other rainbow colours until have a ramekin for each colour.
  • Divide your cotton balls into six piles of 10-15 cotton balls.
  • Start with the first pile, pull each cotton wool ball apart a little bit and place in the jar. Use your skewer or long utensil to push the cotton wool balls down to the bottom of the jar.
  • Slowly pour your purple mixture on top of the cotton balls. Try and pour your mixture so that it covers all of the cotton wool balls. Use your skewer to move the cotton wool balls around gently until they absorb all the paint. You want the cotton wool to absorb all the paint mixture to keep the colour in place without having leftover mixture that can leave into the other colours.
  • You can add more cotton balls as needed.
  • Repeat the above for each layer and colour of the rainbow in this order: Blue, Green, Yellow, Orange, Red.

And bobs your uncle, you should have jar that resembles a rainbow!

A few things we learned along the way…

  • Don’t press down too hard with your skewer once your colour mixture has been added as the paint squeezes out of the cotton balls and may mix with the next layer
  • Keep the jar fairly still when and after assembling so the colours don’t separate
  • Eventually the colours will mix…just like a real rainbow….but they look great while they last

Our chief jammer had a great time doing this with her girls and we hope you have fun too.

If you have a go, we’d love to see your rainbow jars so please share them on your social channels using #jamjarcreations.
