[GUEST POST] DIY Fizzing Bath Bombs Children's Activities / DIY

One of the best things about this time of year is that it’s finally warmed up enough to get outside for some fresh air! Warmer temperatures mean melting snow and that of course means dirty, muddy puddles. A dirty mud puddle is like a kid magnet. I don’t know what it is about them, but kids to a puddle are like a moth to a flame. It’s inevitable that at some point my kids are going to seek out some puddles and do some serious jumping. I’m all about “saying yes” and embracing fun in childhood (and adulthood!), but I’m not a big fan about the ensuing battle to get them clean. One of my tricks is to lure them into a shower with the promise of a fun bath with a simple and easy to make fizzing bath bomb.

There are plenty of products available to make bath time fun these days. You can make your bath water change different colours, turn into gel and back again and even glow in the dark. I love the idea of making baths fun, but I’m not a fan of the chemical additives that are used to make all of these things possible.

Three years ago, on my quest to decrease my family’s exposure to added chemicals, I used my background in biotechnology to develop some all-natural products and launched my small business Love Simply Made. You can read more about me, the products I manufacture and my small business over at www.lovesimplymade.ca and on my Facebook page.

While having a background in chemistry is certainly handy, it’s not necessary if you’d like to have a little fun with your kids creating something that’s safe and fun to use in the bath! I would love to share with you my recipe for Fizzing Bath Bombs. These awesome bombs are made from simple ingredients, all of which are easily found at the grocery store, bulk food store (such as Bulk Barn), or can be ordered online from Saffire Blue Inc. The recipe is super easy, no stress for mom and dad, and the kids get to practice measuring and mixing!

I must do this with the kids! DIY Fizzing Bath Bomb

Bath Bomb Ingredients:

  • Epsom salts
  • Cornstarch
  • Baking soda
  • Citric Acid
  • Optional* turmeric this provides a nice soft yellow colour and it’s all natural!
  • Extra virgin olive oil
  • Water

Bath Bomb Materials:

  • Mixing bowl
  • Small cup
  • Measuring spoons
  • silicone mold – these can be found at the dollar store for very cheap.
  • Whisk
  • small plastic figures such as plastic dinosaurs from the dollar store
  • cookie sheet
  • Jar or container to store your unused bath bombs in

You’ve very likely got several of these things around your house already. The others are easily found in bulk at bulk barn, aside from the citric acid. Citric acid is sold in small 100 g bottles, you may have to ask a store associate to help you locate it. Bulk barn also sells essential oils, now is a great time to grab a bottle of lavender or sweet orange for scent!

Bath Bomb Instructions:

There are 2 ways you can make the bath bombs. There is the fast method with a quick short burst (as seen in the video below) and the second method is for a longer slower fizz which takes 48 hours to cure.

Fizzing Bath Bomb Powder (Quick 5 mins to prepare):

  1. Once you’ve got all of your materials organized, it’s time to have some fun! The basic recipe is very simple. Two parts baking soda, one part Epsom salts, one part citric acid and one part corn starch. This is a very basic ratio, so if the kids get a little messy or it’s not quite accurate don’t stress! The most important thing is to have twice as much baking soda as citric acid. I like to use the whole jar of citric acid and then use that empty jar to measure out the rest, it keeps things nice and simple when kids are involved!
  2. Measure out each of the dry ingredients first into a bowl and whisk to mix so everything is combined evenly. If you’re adding turmeric measure out 2 tsp and whisk that in as well.

Fizzing Bath Bomb Mold (15 mins to prepare, 48 h to cure):

  1. Into the small cup, measure 2 tsp olive oil and 3 tsp water. If you have some essential oils you can add 1 tsp to the wet ingredients now, just make sure to add 1 less tsp of water. Pour the wet ingredients into the dry powder you made above and whisk quickly! It’ll fizz a bit at this point as the water activates the baking soda (the base) and citric acid (the acid) which react together to form carbon dioxide gas and therefore the bubbles.
  2. Place your silicone mold onto a cookie sheet (this allows you to move the mold while it’s drying). Using a measuring spoon or small spoon, spoon the mixture into the cavities of the mold. You want to fill them and pack the mixture down tightly with your fingers. At this stage, I like to hide small plastic toys in the bath bomb as a little extra fun. To do this simply half fill the mold cavity, pop in a small toy and then fill in over top and pack tightly.
  3. Once your bath bomb molds are filled they will need to sit for at least 24 hours (48 is best, but kids aren’t too patient!). This allows the water to evaporate so they harden up and can come out of the molds more easily. Once they’ve had a chance to dry you can remove them from the molds carefully. Store your bombs in an airtight container until you’re ready to use them since they can react with moisture in the air.
  4. At bath time, fill your tub and let you child(ren) pick a bath bomb to drop in. Watch it fizz and bubble!

This is a fun and simple activity to do with your kids that is cost-effective and you can feel great knowing that there are no harmful chemicals in their bath! Alternatively, if you don’t want to wait 24 hours you can omit the olive oil and water and just whisk the dry ingredients into a powder that will fizz when sprinkled into water. It won’t fizz as long since it’s not hardened and concentrated like a bath bomb, but it’s still fun!
