Come learn how to make magic treasure rocks with your kids. Kids will have tons of pirate-y science fun for Talk Like a Pirate Day (or any day)!

Wether you save this activity for Talk Like a Pirate Day (Sept. 19) or you add it to your preschool science lessons, your little ones are going to love exploring chemical reactions as they uncover hidden treasures.

Change up the “treasure” to match your child’s interests, and your preschoolers will beg to do this preschool science activity over and over again.

Magic Treasure Rocks

This activity is just plain fun! Kids will be amazed when they discover the hidden treasures inside each “rock”. But, it’s not just fun.

Explain to your preschoolers that when they pour the vinegar onto each “rock” (which is made with baking soda), they’re seeing a chemical reaction occur. When the sodium bicarbonate (baking soda) reacts with the vinegar, carbon dioxide gas bubbles are being formed.

What You’ll Need

• 1 box of baking soda

• 1 bottle of white vinegar

• food coloring, assorted colors

• little treasures (toy rings, gold pieces, etc.)

What You’ll Do

Put about 1/3 cup of the baking soda in a small bowl. Add about 4 teaspoons of vinegar and 3-4 drops of liquid food coloring. Mix together well. It should be a very thick paste consistency that you can roll into a ball.

Take one of the small treasures, and put it in the baking soda mixture. Roll the mixture into a ball so that the treasure is completely hidden inside the ball.

Repeat steps 1-3 until you make as many treasure rocks as you want.

Set the treasure rocks on a baking sheet, and let them dry for 24-48 hours. They will dry faster if you set them out in the sun.

Fill a squeeze bottle or spray bottle with vinegar. Put a treasure rock into a dish, and spray or pour the vinegar slowly over it. Watch the treasure rock foam up as the chemicals begin to react.

Kids will love the treasures they find inside!
