S.T.E.A.M. Craft | Heart Eruption

Turn a classic experiment with vinegar and baking soda into a work of art! The chemical reaction between the two common household ingredients never gets old. When an acid and a base mix, they form a gas called carbon dioxide. Here the vinegar is the acid and the baking soda is the base. In addition to watching the hearts erupt, watching the colors combine to create one of kind patterns will make you want to do it again and again. 

Using the shape of heart for Valentines Day, this easy afternoon project transforms into a keepsake that you’ll treasure forever and it’s actually frame worthy! 

WHAT YOU’LL NEED:

  • Watercolor paper
  • Heart pattern (we used a cookie cutter)
  • Two foil lined baking sheets
  • Baking soda
  • Spoon
  • Vinegar
  • Medicine dropper
  • Muffin tin or small cups
  • Food coloring
  • Optional for framing: picture frame, plain white sheet of paper and glue stick

WHAT TO DO:

STEP 1
Use a heart pattern to trace hearts on the watercolor paper and cut them out. Place the cut hearts onto a foil lined baking sheet for easy clean up.

STEP 2
Using a spoon, generously sprinkle baking soda over all of the hearts. (Remember the more baking soda, the bigger the eruption!)

STEP 3
Fill each muffin tin, or small cups, with a 1/4 cup vinegar and add your choice of food coloring and coloring combinations and give it a stir.

STEP 4
Using a medicine dropper gently squirt the vinegar mixture over the hearts and watch the fizzy action.

STEP 5
Allow the hearts to set for 5 minutes, then gently lift and place on another clean foil lined baking sheet for drying. Once dry, rub the baking soda off of the hearts gently and dust with a paper towel.

STEP 6
Select your favorite hearts, swipe the backs with a glue stick and glue to a white sheet of paper that you’ve cut to fit the size of your frame. Fame and admire all that science and art!•
