My son’s 4th birthday is next week and he has decided that he wants to combine all 3 of his passions: LEGO, superheroes and ice cream, into 1 awesome party.  So a “Superheroes Love LEGO & Ice Cream” party I’ll do.  Why not, you’re only 4 once, right?

I’m trying to keep this party small and easy.  Four year old’s don’t expect much so why go overboard!

I always try to include cute, practical stuff in the goody bags.  As if kids need more cheap plastic toys.

Lego Soap

I have seen LEGO soap on Pinterest which I knew the boys would love.  But when I went to Michaels to buy the soap supplies I was shocked at the cost.  I would have to pay $3.99 per dye colour, plus the cost of the soap, soap mold and essential oil.  It would have added up to $50.  So instead I thought maybe I could just buy the soap ($9.99 used a 50% off coupon which made it $5.00) and 1 essential oil jar for $1.99.  I thought I could use a silicon muffin tin I had at home to make clear soaps with LEGO pieces floating inside. I really had no idea what I was doing but I thought for $7 I would give it a try.

And it worked!

Now I didn’t entirely think this project through.  Turns out we made a very exfoliant soap (once the soap dissolves the LEGO pieces aren’t exactly soft).  But my kids have been using the soap in the tub, and they love trying to wash themselves enough to get to a LEGO piece.  Boys wanting to clean themselves is a win win situation. Don’t you think?

LEGO Soap Instructions:

(Wow this picture makes the muffin tin look really dirty, I swear it didn’t look like that in person.  That’s kind of embarrassing).


  • 1 block of olive oil soap
  • essential oil
  • a handful of LEGO
  • a silicone mold (I used a muffin tin but you could also use a bread pan and just cut the soap into squares)

Total cost $7.00  and the block of soap made enough for 9 good size soaps.

Cut soap into the pre-marked squares.

Place about 10 of the squares in a microwavable dish and microwave as directed on soap box.  Mine was for 40 seconds.  Stir.  Then continue to microwave at 10 second intervals until soap has fully melted.

Once soap is melted add 5 drops of essential oil per square that you melted. Stir.

Pour soap mixture into molds then add LEGO pieces.  I used a popsicle stick to push the LEGO down.  Remember the soap is still hot, but don’t worry it doesn’t melt the LEGO.

Let the mold sit on your counter for a good 30 minutes to solidify (this time will vary depending on how large your mold is).  My husband thought that if I cooled them at room temperature rather than in the fridge the soap would stay clear (I wanted to see the LEGO pieces as much as possible).  But I don’t know if this is true or not.

And now the part that I thought would be a disaster.  The removal.  To my surprise (since these types of projects NEVER work out for me) the soaps just slipped out of the mold with a little push from the bottom.  Couldn’t be easier.

I picked up these little cellophane bags at the dollar store (40 bags and the little ties for $1).  Wrapped each one up and we are done!  Easy peasy goody bag gift.

My boys LOVED these soaps.  It looks like I’ll be making another batch very soon.

Really the possibilities are endless with what you could add in here.  I’d love to hear some of your ideas…

Check out the LEGO crayons I made for $3.00.  Makes a great gift.

  1. Besides food, olive oil has been used for religious rituals, medicines, as a fuel in oil lamps, soap-making, and skin care application. The Minoans used olive oil in religious ceremonies. The oil became a principal product of the Minoan civilization, where it is thought to have represented wealth. The Minoans put the pulp into settling tanks and, when the oil had risen to the top, drained the water from the bottom.[

  2. This is great , never thought of soap. Also wonder if a mega bock would work as a mold?

  3. This is just wonderful!!! I will have to try and make some for my nephew!
