How to Make Bath Crayons

Come on and get the kids' hands on skills running these school holidays by making bath crayons! You read that right, these crayons are a fantastic way to get the kids into crafting, the best bit? You can use these crayons in the bath to wash up after!

What You'll Need

• Lip Balm Tubes
• Melt and Pour Soap
  
• PC Dye
  
• Optional – kid friendly fragrance

This project is such a fun and simple activity! 

Step-by-Step Instructions:

1. Plan Your Colours
   Decide how many crayons you want to make, why not one for every colour of the rainbow? Each lip balm tube holds about 5ml of soap.

2. Melt the Soap
   Cut your melt and pour soap base into small chunks and place in a microwave-safe jug. Heat in short 30-second bursts, stirring in between until fully melted (but not boiling).

3. Add Colour (and Scent)
   Stir in a tiny amount of PC Dye for each batch, start small, as the colour is concentrated. If using fragrance, add a child-safe soap-compatible scent and stir well.

4. Pour Into Tubes
   Carefully pour the coloured soap into your lip balm tubes. Work quickly before the soap begins to set. Use a filling tray if you have one to keep everything steady.

5. Let Them Set
   Allow the tubes to cool and fully harden. Once solid, they’re ready to use!

You will end up with an array of wonderful coloured crayons for bath time, these can be used to draw fun designs on the side of the bathtub, the best bit? It's soap so it washes right off!

Frequently Asked Questions

How do bath crayons work?

Bath crayons are made from melt and pour soap set into a solid stick shape. Because they are soap, they let you draw fun designs on the side of the bath or on tiles, and then wash straight off with water.

How much soap does each crayon need?

Each lip balm tube holds around 5ml of soap, so plan your batch based on how many crayons you want to make. Making one in each colour of the rainbow is a fun option for kids.

Can I add fragrance to bath crayons?

Yes, but only use a child-safe, soap-compatible fragrance and add it sparingly. Stir it through well before pouring. You can also leave the crayons unscented if you prefer.

Will the crayons stain the bath?

Because the colour comes from a small amount of soap dye, use only a tiny amount as it is concentrated, and the marks are designed to rinse off. It is still worth testing on a small area first and wiping surfaces down after use.

Is this a safe activity for children?

It is a great school holiday craft, but the soap is melted in a microwave and is hot, so an adult should handle the melting and pouring. Let the crayons cool and set fully before children handle or use them.
