1. DIY the Decorations
Stick splatter shapes cut from colorful poster board onto your walls with phrases like “Slime Station!” Customize paper lanterns: Squeeze puffy paint onto the top rims so they look drippy. Go back over areas to make them gloppier.
2. Pick the Right Recipe
A school-age kid probably has a preferred recipe, but for little kids, use an edible one. We like this recipe from The Soccer Mom Blog: Mix 1/2 cup cornstarch and half a 3-oz. pkg. of sugar-free gelatin. Stir in 1 Tbs. water at a time, until mixture clumps (you’ll need about 1/4 cup).
3. Save Your Sanity
Have some slime already made so kiddos can start the fun ASAP. Let half of the kids play with premade slime while the other half makes their own batch, then switch.
4. Make It Unique
Now it’s time to personalize those blobs! Move kids to a table that has measuring spoons, food coloring, figurines, and bowls of sequins and glitter. Psst: Use baby wipes for cleanup here!
5. Play a Gooey Game
Fill a bucket with slime and toss in one small toy per child. Have each child try to pull out a specific toy (an eraser, a ball) so they have to feel around for it!
6. Top It Off With Cake
For a goopy treat, fill a pastry bag with instant pudding dyed with food coloring and drizzle it down any cake’s sides, says Amanda Rettke, author of Surprise-Inside Cakes.
7. Send the Fun Home
A slime kit is the perfect favor! Fill a zip-top bag with ingredients and the recipe.
