Halloween Sensory Activities for Toddlers

Sharing is caring!

This halloween sensory activities for toddlers is super easy to make! My toddler loved this project! It was cheap, quick, and easy to put together. It kept him entertained for at least 30 minutes.

This recipe makes a lot. My original plan was to make it into balls or other objects, but he liked just scooping the mixture into his tray and pouring the vinegar on.

Definitely make sure you have a deep dish to put this in. The foam quickly expands and can make a big mess if you’re not careful.

Even though I warned him multiple times not to eat it, he did stick his face into the mixture while trying to blow the foam towards the end. He immediately yelled for me because it tastes gross (I mean it’s mostly vinegar at the end). 

At least I know it’s all natural so nothing toxic to worry about!

If you want to add food coloring in you can. I split the batch in half and added food coloring to half and left the other half white.

My two year old didn’t care about the food coloring honestly. He was most interested in the erupting, the feeling of the foam, and pouring the liquid.

Overall, it was an awesome little science craft. We got to talk a little bit about reactions, although I think most of it was over his head. 

This was a perfect spooky activity for our 31 days of Halloween countdown!
