Growing up, St. Patrick’s day was not a particularly big deal for me or my family. Of course we wore green so we wouldn’t get pinched. But that was about the extent of our celebrations, as far as I can recall. But I’ve been inspired by so many wonderful St. Patrick’s activities I’ve seen online to do a bit more with the holiday with my own kids. And I knew this magic leprechaun rocks activity would be huge hit with both of my kids.
You might be asking: What are magic leprechaun rocks? Well, they are magic rocks that disappear in a burst of bubbles when “washed,” leaving behind some leprechaun gold.
Note: Find more St. Patrick’s fun on my St. Patrick’s Day activities for kids page.
One day I came upon a post about “dissolving rocks” at Reading Confetti. That post provided the inspiration for my magic leprechaun rocks!
Preparing the magic leprechaun rocks
I had to prepare the magic leprechaun rocks a day in advance. I mixed approximately 1 cup of baking soda with 1/4 cup of water that had been dyed green with our liquid watercolors. Then I molded the dough into balls, sticking a gold coin in the middle as I went.
The dough should be moldable but not too wet. The first time I made the rocks, my dough was too wet. I laid them to dry but five minutes later they had melted into puddles. I put them back in the bowl, added more baking soda, and re-formed the rocks.
This time the rocks held their shape, and I let them dry overnight. By morning, they had turned into hard, green, magic leprechaun rocks.
Enjoying magic leprechaun rocks with kids
The day we did the activity, I hid the rocks in our backyard while the kids were napping.
When the kids woke up, I told them that leprechauns had come and left them some surprises in our backyard. The kids couldn’t get their shoes on fast enough to go searching for their surprises! QBoy quickly located the first magic leprechaun rock.
I told him, “That looks dirty, we should clean it.” And I directed him to dump it into a bowl I had filled with vinegar. When he dropped it in, more fun ensued as the rock fizzed and bubbled up, much to the kids’ delight!
After seeing the first magic rock, the kids eagerly gathered up the rest of the rocks hidden around our yard and added them to the bowl to be “washed.”
After a bit, the kids noticed the first piece of leprechaun gold appear in the bowl.
Of course, they had to scoop them up.
I brought out a container for the kids to collect their leprechaun gold.
And the kids had all sorts of fun playing with their new leprechaun gold. 🙂

My magic leprechaun rocks have been really popular. I bet your son will love them! And I’m glad he has been enjoying my printables too!
I saw this activity the night before our preschool Saint Patrick’s Day celebration and had to do it!!! I baked the rocks at 150 for 1 hour and they were hard and ready to go. I CAN’T WAIT for my class to engage in this activity!! Thanks for sharing!!!!
Oh how fun, I’m sure your kids will love it!!
This is so fun! About how many rocks does one batch make?
It would depend on how big you make the rocks, but I seem to recall that our batch made quite a few.
What an absolutely awesome idea! Going to have to pin this one 😀

This is fantastic and I’ll definitely be doing this with my little ones! It got me thinking of using this idea for Easter. Could you put Easter eggs wrapped in foil or would the baking soda and vinegar dissolve the wrapper? Anyone have suggestions what Easter surprise you could hide?
I have been thinking of doing something similar for Easter as well. I guess we’ll have to experiment to see what might work!
How awesome for the kiddos! You are a genius!
Thank you for this, my kids had a BLAST today finding these outside, what a cool idea. they came up with so many different ideas on how they got there, great fun!
Aww, thanks so much for sharing with me how much they enjoyed it!
Hi Katie,
I just made them now before going to bed. We are celebrating tomorrow as some kids were absent on Tuesday and I had a doctor appointment. I am sure the kiddos will love this activity! Thank you so much for making my lesson plans be so much fun.

This is awesome!! I’m going to make these for my children’s kindergarten classes! Thank you for sharing this!
I’m so pumped about making these for My Kinder class and the other K classes for our fun St. Patricks day activities!!!
I hope they love them!
Sounds wonderful! But won’t the food coloring stain badly and be hard to remove from the children’s skin if they are making the rocks? Is there a better solution to use that doesn’t stain skin or clothes… THANKS!!
The liquid watercolors we use are washable from most fabrics. Sometimes their skin will get stained for a bit, but it usually doesn’t last more than a few hours before washing off.
I cannot thank you enough for all the inspiration and freebies that I have used for my autistic granddaughter aged 7. I feel guilty at times that I have downloaded so much however when using these downloads for speech, writing, alphabets, counting and endless other activities you are with me and inspiring me to keep going with the therapy etc. Thank you so much, you are truly appreciated.
Thank you so much for your kind and thoughtful note! I am honored to know that I can support you to do the best for your granddaughter.
Great idea! I think I will do this with my gifted group and have them write directions on how to find the rocks .
Where did you find the gold coins? Were they US 1$? I assume fake plastic ones might fall apart in the vinegar?
They were fake. I assume they were plastic but I honestly can’t remember now as we did this activity a few years ago. We didn’t have any problems with the coins falling apart in the vinegar.
Thank you for the quick reply!
