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.

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. 🙂
