Make Slime with Borax

Edited by Sarah Maloney, Eng, Inukshuk


You've probably seen people being slimed on Nickelodeon. Until 2015, the Nickelodeon studios actually had a slime geyser that would shoot slime every 15 seconds. Kids love mushy, squishy, squidgy slime and though you might not want a slime geyser in the front yard, this recipe will show you how to make enough slime for a super slimi-fied party!

This How To is split up into sizes of slime festivities Small Slime and Super Slime. Whether it's a birthday party, an end of the school year party or just an excuse to get together and get slimy these activities are sure to make for a gooey bash. Slime also works as an educational activity and science experiment.

Small Slime

This activity works best for ages 6 and up and can be done indoors. You will want to set up the slime stations for each participant beforehand.

Start by explaining the activity to participants. Don't be surprised (especially for younger ages) if some kids seem apprehensive about the activity. Not all kids enjoy getting mucky. You can be inclusive by partnering participants up and allowing them to work together. Also consider a 1 page handout at each station outlining the activity. Work as a "teacher" as you move participants through the steps. Demonstrate in an area all participants can see you and walk around to ensure everyone is following along. If you have more than 10 stations consider having an additional adult to supervise.

Materials (Per Station/Participant)

  • 2 cups for each station.
  • 1 ½ cups warm water.
  • Popsicle sticks to stir
  • 1 tsp of Borax Powder (find it in the laundry detergent aisle).

  • 1/2 cup of school glue. Plain white school glue is the most consistent for this craft. We found clear glue made the slime too sticky and not as pliable. You can also consider glitter glue or glow in the dark glue, but ensure it is "classic" (not clear). Consider creating a "glue" assortment for participants to choose from.
  • A selection of food colouring (optional). You can use neon food colouring. Add this to the glue collection and participants can choose what kind of slime they'd like to create.
  • Small plastic sealable containers (you can get these at the dollar store) or baggies so participants can take their slime home with them.


  1. 1
    For younger participants, consider having the ingredients pre-measured in the cups
    Participants 7 and up can probably use measuring spoons with ease.

Super Slime

If you're really brave and can plan an outdoor party in the warm weather, you might consider making large quantities of slime for outdoor play. These activities work best for participants 9 and up. Ensure you let parents know before the party what is planned so participants can arrive with bathing suits and a change of clothes.

Materials for Super Slime

For the Super Slime you want to make it more liquid than solid. This type of slime works best with cornstarch. The recipe is one part cornstarch to one part baking soda to half cold water. Your choice of food coloring can be added in for color.

The easiest way to do this is to mix the cornstarch, baking soda, cold water and food colouring in buckets outside. This base recipe will make about 2 cups of slime. You can double or triple it as needed.

  • 2 cups baking soda.
  • 2 cups corn starch
  • 1 cup cold water
  • 10 drops of food colouring.
  • Large buckets to mix the slime and smaller buckets or containers for activities.
  1. 1
    Pour the corn starch and baking soda into a bucket

  5. 5
    Add more water if you need it more liquid and more cornstarch if it is too thin
    You want it to be about the consistency of gravy.

Super Slime Games

  • Duck Duck Goose. Like the traditional game, but when the person outside chooses the "goose" they drop the contained of slime on the person's head and take off running. NOTE: This can get slippy so ensure you have the space for slips and falls.
  • Slip N Slime. Set up the slip n slide with water, but as kids are sliding down, throw slime on them.
  • Scavenger Hunt. Fill a kiddie pool with slime. Hide various dollar store items (plastic toys, balls, etc.) in the slime. Participants get to find as many items as they can.

  • Bucket Balance. Much like the egg on the spoon game, fill a bucket with slime, place it on participants heads. Participants must walk from one spot to another without spilling the slime.

Clean Up

  • Have hoses available for a hose-down.
  • Wash off stations such as sprinklers, hoses, super soakers, kiddie pools.
  • The Slime is washable and can be disposed once diluted and sprayed with water from the hose.
