Ideal Age Range:

I prefer to make the slime myself and give it to the kids to play with. If that is what you are doing 3+ is a great age range, just monitor younger children. If you want your children to help then 5 – 8 is ideal to help and not make a huge mess.

Mess Factor:

Low. You can contain the mess while you are mixing this up. The slime left some residue on the table, but if you mix the right consistency you won’t have any other mess issues.

Prep Time:

Less than 10 minutes!


How to Prep:

1 week before you want to do this, set yourself a calendar or task reminder to purchase any supplies you don’t have from the list above.

Once you have the ingredients, you really just need to mix them together. I used a plastic container that could be thrown in the dishwasher for easy clean up and a regular spoon.

Step 1 – dump the bottle of glue into the container and stir a little.

Step 2 – add the slime activator in 1 tsp increments.

  1. Dump the entire bottle of glue into the container. It will be hard to get all of it out, I used most of a bottle and it was fine (it also left a little for other projects).
    • If you have regular glue at home that you’d prefer to use, that is fine. You can add glitter (or other decorations) separately, I just think it is WAY easier to eliminate that step.
  2. Follow the directions on the slime activator, adding it 1 teaspoon at a time. I used about 8 tsp. to get my desired consistency. Stir for a while until you are close to your desired consistency, then use your hands to knead the slime to get to the finished product.
    • About half way through, this slime will be WAY too sticky. If you put your fingers in to knead it, it will stick all over your hand. Keep adding activator. The slime will be ready when the slime sticks to itself and not your hand.
  3. Package the finished slime in any container that you wish. (I used a simple Ziploc bag.)
  4. Repeat with another bottle of glue to create a different color.
    • I made pink + green for our recent camping trip. I will probably make more for our next trip, making sure that each kid gets their own color. One bottle of glue is the right amount for one kid to play with.

A quick note about consistency – you can really choose to make the slime however you want. The reason I recommend using more activator is to avoid the mess. Too sticky slime tends to get everywhere in my house and my kids don’t like playing with it as much when it just makes a mess.


Added creativity: 

You can play around with adding embellishments to the slime. Pony beads, glitter and other harder objects should mix in well (just be careful with smaller children and choking hazards). You can pair different colored glue and embellishments to make slime for different holidays (Valentine’s Day, St. Patrick’s Day, Hanukkah, Christmas, you get the idea).

Active Instructions:

No active participation needed from you. Give the kids the slime and let them play! This is great for a camping trip or something where you will be outside at night to really see the glow-in-the-dark element, but the slime is just as fun during the daytime.
