Kids of all ages will enjoy the health benefits of handwashing with this fun glycerin soap!

With the release of Avengers: Infinity War this week, my kiddos are wanting to make all sorts of fun Avengers themed crafts. Our most recent creation being “Avengers Soap”: a bath soap with a small toy in the middle of the soap that is totally easy and fun to make! The more soap bubbles they make, the closer they will be to getting a surprise toy.

Let’s promote good hygiene with child’s play.

Why use normal soap if you can make your own soap and add tiny toys in the middle? The thing I love about making homemade soap is that you can make all sorts of shapes, colors and add all sorts of things into the soap including different fragrances. The first time we made toy soaps, we added lego minifigures. Last year, we made transparent soap with dinosaur toys.

Since then, we’ve made so many different colors and little toys. There are just so many great ideas to try. And best of all, convincing my little ones to shower and take care of their personal hygiene got much simpler, too. My older children seem to enjoy this handwashing approach too. We just know these habits will stay long term with them.

Over the years, my kids have learned how to make soap and look forward to our next creation. Not only are they very easy to make, but they last a long time and make bath time so much fun. This year’s DIY soap includes characters from Marvel Comics – yay! These soaps also double as great gifts for a young birthday boy or girl.

The best part is, homemade melt and pour soap recipes (like this one) allow you to use the soap right away! Plus what kid doesn’t like surprise toys?

So, let’s make some fun Avengers Soap bars that allow your child to have an Avengers toy surprise once they are done using the soap!

AVENGERS SOAP

What you need to make Avengers Soap:

- Clear Melt and Pour Soap Base
- Avengers Toys (we found these Avengers paperweight chest pieces at the dollar store, but any toy that is made of hard plastic will work)
- Rubbing Alcohol in a Spray Bottle
- Soap Mold (we used silicone molds)
- Microwave Safe Measuring Cup
- Essential Oils (1-5 drops go a long way)
- Soap Cutter or Knife
- Cutting Board
- Microwave

How to make Avengers Soap:

Step 1:

Start by cutting your soap into small pieces using your soap cutter or knife. This helps the soap melt evenly while in the microwave. Place the pieces into your microwave safe measuring cup or bowl. You can also use a double boiler if you have one.

Step 2:

Prepare your soap mold. I like to place mine on a hard surface and sometimes the cutting board if needed so it will have a stable bottom (this allows it to harden evenly). Take your rubbing alcohol and spray your Avengers toys liberally. Spraying the toys BEFORE you pour the melted soap onto them helps adhere the soap to the toys. Don’t skip this part!

Step 3:

Next, place your soap pieces into the microwave for 30 seconds. Remove and stir. You want to repeat this until all of the soap is melted. Note: Don’t try to melt it in increments longer than 30 seconds, it will cause hot spots in the soap where soap will burn while other pieces don’t melt and it will cause a hot mess.

Step 4:

Once melted, add your essential oil. You’ll want to use about 1-2 drops and stir them into the melted soap base.

Place your toys into the middle of your soap mold cavity. One toy per soap mold cavity.

Carefully pour the melted soap on top of the soap molds filling each soap mold cavity entirely.

Note: If you are using lightweight toys or toys that are too heavy, you may need to use a spoon or stick to push them down into the soap until the soap begins to harden. This will help the toys fall to the bottom of the soap.

Step 5:

Finally, spray the tops of each cavity with the rubbing alcohol to remove any trapped air bubbles (helps the soap be more transparent).

Now is the hard part – you need to let the soap harden for several hours (minimum of 4 hours) but overnight is best. You want it to become as hard as possible so you can pop it out from the mold without breaking the soap.

Step 6:

Once hardened, gently pull the sides of the mold away from the soap and flip the mold over. Press gently on the backside of the mold and the soap will pop right out. Your soap with a visible toy is ready for immediate use or you can store away for future use. You do need to cover the soap in a sealed baggie or use plastic wrap to keep it from air and moisture.

Something SUPER IMPORTANT worth noting – never ever use fragrance oils unless they are skin safe. Pure grade essentials are fine to use in crafts like this.

However, there are some fragrance oils sold down candle isles at retailers like Walmart and these are NOT skin safe. They can cause chemical burns. So, please be careful and ensure you use 100% pure grade essential oils or skin safe fragrances. We highly recommend following these basic safety tips for using essential oils.
