Ingredients for the Watermelon Slime Recipe for Kids

Watermelon Slime Ingredients; pictured: liquid starch, water, black rocks, spoons, foam beads, glue

1 (5 oz.) bottle clear glue. If your slime isn’t edible (and this one is not) it probably has glue in it. Glue is the perfect component to add the sliminess.

½ cup liquid starch. Liquid starch is necessary for making slime stretchy.

½ cup warm water. Water balances out the chemical reaction between starch and glue.

1/2 cup Pink foam balls. These cool foam balls add texture and color.

1/2 cup Green foam balls. These are so much fun to play with!

Small black stones. Don’t forget the watermelon seeds!

Mixing bowl (2). Make sure you use mixing bowls you don’t mind getting messy. Slime is gross and sticks to everything during the mixing process. It cleans up pretty easily with warm water though!

Mixing spoons (2). Again, use spoons you don’t mind getting sticky and gooey. If you have favorite spoons don’t use them for this!

Here’s what always happens to me. My kids use my favorite spoons to make gross stuff, and leave them on the counter all a mess. I’m distracted and don’t finish clean-up right away. When I come back to the kitchen to make supper, my favorite spoons are not available for cooking.

Plastic mat. This will keep everything from sticking to your table or countertop.

How to Make Watermelon Slime

The best part about making slime is the mixing of it and watching it all come together. So in my opinion, your kids should do all of this part themselves, with your supervision and help as needed.

Slime is great to make with older elementary kids and tweens. Anyone younger than seven or so is going to need a lot of help, but it can be a great sensory play tool!

1. Pour the glue into the mixing bowl. 
2. Add the warm water.
3. Stir well until the glue and water are mixed.
4. Pour the liquid starch into the mixture and stir. Continue stirring until the mixture turns cloudy.

It’s ready to go! I like to use a plastic mat under everything for our sticky recipes to make clean-up easier.

You can get creative when you play with it by making watermelon slices, half of a watermelon, or a whole watermelon shape. Add the black stones to represent the seeds of the watermelon.

Tip: If you have watermelon at lunch, save and rinse the real seeds to use in place of the little black stones.

Tips for Success
