Jiggly Goop

Guest Post by Lauren of Tutus & Tea Parties
This soft and jiggly sensory goop is a great new sensory experience for your littles. They will enjoy molding this gooey texture for quite some time.


I was looking for something fun to play with on a rainy day and realized I didn’t have many ingredients to make something new to dig our hands into. After browsing the cabinets, I decided to make some goop (water & cornstarch). That’s when a box of Knox Gelatine fell out and gave me an idea.
I was curious to see what would happen if I mixed some Gelatine with the water for the goop and this is what it came out to be. A jiggly, squishy goop that was soft & gooey to the touch. It was super fun & I hope you enjoy it as much as we did! 
Jiggly Goop Recipe:
1 Pack of Knox Gelatin
1/2 cup of cold water
1/2 cup of boiling, hot water
1 cup of cornstarch ($1 at Walmart)
Empty your pack of Knox Gelatin into a bowl. Add the cold and hot water, and then stir until the gelatin is dissolved. Add in the cornstarch. Place in the refrigerator for an hour (or more) until it has cooled and stiff. Scoop out onto your play surface and add in play materials as you choose. (We used sprinkles.)

  1. Oops.. You probably didn’t mean the whole box of gelatin! I thought you did because the pic showed the empty box. :( I salvaged the fun though but putting the rather hard glob, cut into pieces, into my vitamix with hot water. Blended till smooth, then gave it to the kids outside with a mound of extra cornstarch. They’re still playing. It’s runny, definitely not moldable, but still fun!

  2. This looks like so much fun! I especially like the additions of the sprinkles! I will be trying this soon with my two little girls:)

  3. I was wondering if you meant just one of the four packs inside, or the entire box of knox gelatin. From the comment above, I guess you meant just one of the four packs though. This looks fantastic and I am definitely pinning this to do with my kids!
