October has so many great opportunities for integrating themes into the curriculum with fun experiments. Kids especially love any opportunity to be “scientists.” Kick-off some Halloween fun with this exciting Monster Mixing Potions experiment!

Bring the thrill of the Halloween season to life with the opportunity to make “potions!” This is the perfect activity for any primary or elementary-aged student. The suspense will have them on the edge of their seat!

In order to begin, you’ll need to gather the items below:

Monster Mixing Potions Items

Start by allowing the kids to get creative decorating the cups with monster faces. Look to the book Go Away, Big Green Monster! by Ed Emberley for inspiration. It’s a classic and it sure won’t disappoint! Give the monster faces plenty of time to dry before doing the experiment.

Once they are ready you can decide whether you will reveal the “potions” (experiment materials) needed or not. Students can observe, smell and make predictions if you’d like them to. Place as few or as many drops of food coloring as you’d like at the bottom of the cup. After, sprinkle about a teaspoon of baking powder over the coloring. Pour the vinegar into a small bowl and allow students to combine the “potions” using the eyedroppers.

I love that Learning Resources created a product that enables students of all ages (3+) to use tools that allow them to truly feel like a scientist. These jumbo eyedroppers are perfect for experiments and fine motor sensory play in the classroom. They are easy to use for tiny hands and fingers and hold quite a bit of liquid, which worked well for this experiment!

After the vinegar is in the eyedroppers, allow the kids to carefully and slowly drop a drip or two of the vinegar into the cup and observe the reaction of the potions combining.

They can gradually add more vinegar and baking soda as needed. Be careful of the surfaces you choose to do the experiment on. Take a look at the chemical reaction below! Students will be roaring with laughter and erupting with questions once the reactions take place.

Monster Cup Reaction

Just a quick note, you’ll need about ¼ cup or so of vinegar to elicit a potion with a reaction as seen in the pictures above and below. Also, I recommend placing the cup on a tray for easy cleanup!
