Jell-O Building Blocks
Activity DesignerMarcella Campbell
Can you really make edible building blocks? Yes! They're pretty, fun, and require no specialized skills (unless you count heating and pouring). They're a great rainy day activity, and they make really fun party favors. The biggest challenge is keeping them uneaten long enough to play with them!
What You'll Need
- jello (1 3 oz. box) - We made 3 2-oz. blocks per color. Regular ice cube trays are 1-oz.
- nonstick pan - optional, but it made cleanup much easier!
- baking sheet (optional)
How We Did It
You'll want everything handy before you start. For blocks, you can use cube-shaped candy molds or just an ice cube tray. (Keep in mind that the molds we used make 2- and 4- oz. cubes, while standard ice cube trays make 1-oz. cubes.) You'll need at least one 3-oz. package of Jello and 2 small unflavored gelatin packets per color. (For 6-oz. packages of Jello, you'll need to use 4 gelatin packets.) If you're using a silicone tray, you may want to set it on a baking sheet so it's easy to move once it's full of hot gelatin.
Carefully place your mold in the refrigerator. Refrigerate until completely cold and set, about an hour.
Grown-up step: To unmold, very carefully pry the blocks out with a toothpick or butter knife. (Don't worry -- they're much sturdier than they look.)
If desired, dust the bottoms lightly with cornstarch or powdered sugar so they don't stick together when you stack them.
