Simple bath bombs DIY for children

03 July, 2024

Watch your child’s eyes light up with wonder as they watch the bath bomb they made themselves fizz and dissolve in their bath!

A bath is a great way to wind down, warm up and relax before bedtime. But some children need enticing to actually get in! Give your children a bathtime treat with a bath bomb or two. They’re easy and inexpensive to make using our easy bath bomb recipe – you probably have all the ingredients in your kitchen cupboard!


What is a bath bomb?

A bath bomb is a solid mass, designed to fizz and dissolve in the bath, scenting the water with ingredients that can soften or exfoliate the skin. Children love the fizzing noise they make when they hit the water and the feel of the bath bomb as it slowly breaks down in their hands underwater. You can make bath bombs a special night of the week treat, a reward for good behaviour or just bring them out when you need a little extra enticement (okay, bribe) to get your children to have a bath!


Benefits of making bath bombs together

Children may be curious about how to make bath bombs. Making them together is a fun activity, with opportunities for children to learn about maths, art and science as they measure out ingredients using cups, spoons and scales, shape the bath bombs into moulds and build their decision-making skills by choosing their favourite colours and scents to add. You can ask them to hypothesise what they think might happen when their bath bomb recipe ingredients mix together, then hit the water and talk about chemical reactions and how solids can change to liquids. Children can also focus on their senses as they learn how to make bath bombs, feel the different textures of the ingredients and smell the essential oils.
