Lego Bath Bombs

Lego Bath Bombs

Being a mum of three boys and a girl I am always trying to find activities for the kids to do. We love creating and love to give Australian handmade gifts. These Lego Bath Bombs are perfect handmade gift ideas for Christmas and just a little messy fun for the kids to make too (it was quite humid the day we made these ones).

Lego Bath Bombs - Ingredients
Makes about 12 balls.


  • Bicarbonate of soda – 2 cups (great for skin conditions)
  • Citric acid – 1 cup
  • Corn flour – 1 cup
  • Epsom salts – ¾ cup (muscle soreness)
  • Rock salt – ¼ cup (muscle soreness and detoxing)


  • Water – spray bottle
  • Lavender oil (or any oil that you would like to use, we use lavender for calming and destressing)
  • Oil (we used Bio-Oil, cause that is all we had, almond oil is excellent for the skin)
  • Food colouring (optional)

Lego Bath Bombs

Mix all the dry ingredients together, use a whisk to mix in the ingredients evenly.

Mix in the oil, food colouring and essential oil. You might see a slight reaction but not that much and don’t worry if you don’t see any at all at this stage. Using you water spray bottle, spray your mixture with a bit of water. Don’t spray too much you don’t want the mixture to be too mushy otherwise it will react too much.

We used our silicon muffin trays to make our bombs but you can use an old tennis ball cut in half.

Place the mixture in the moulds, use a lot of pressure. Then place the Lego man on top and then press him into the mixture, then cover (you might notice that the mixture may grow a bit, this is due to the moisture or humidity in the air).

We let the bombs dry overnight or if it is too humid we popped them in the oven for about 15 minutes on 70 degrees just to dry them out a bit. Be careful wrapping the bombs they are very delicate but the perfect handmade gift for friends and family.
