We have made slime before but I haven’t shared it on the blog until today. Our first (and definitely not our last) slime recipe is this amazing Mess Free Glow in the Dark Slime! My kids absolutely loved this one. This slime is perfect for all kids and even adults! I have to admit I had a hard time putting it down. And the fact that it didn’t leave a mess was such a bonus!

How to Make Mess Free Slime

The key to making mess free slime water. The more water you add the softer and messier the slime will be. You will see this recipe has water as an optional ingredient. If you want a mess free slime skip the water. If you want a softer slime include water in your mixture.

  • 5 oz Bottle of Elmer’s Glow in the Dark Glue
  • 1/4 tablespoon of baking soda
  • 1 1/2 tablespoon of contact lens solution (contact lens solution must contain boric acid and sodium borate your slime will NOT work without it)
  • 2 tablespoons of water (optional)

How to Activate Your Slime

To activate your slime you will need contact solutions, but not every contact solution is created equal. Make sure to purchase slime that has boric acid and sodium borate as the main ingredient. The brand that I like to use is Renu Fresh. If you use a contact solution without these ingredients your slime will not work.

How to Make Glow in the Dark Slime

Empty the entire bottle of Elmers Glow In the Dark glow into a bowl. To make a good amount of slime you will need the entire bottle. To get the reside, use a box cutter to cut open the top of the bottle and use a craft stick to scrap out as much of the glue as you can.

Next add 1/4 tablespoon of baking soda and mix thoroughly with the glue.

Optional: Add 2 tablespoons of water. The water will make your slime a little messier. So if you want to mess free skip the water and head straight to the contact lens solution. Your slime will still be soft and stretchy and it will also be mess free. Add water if you want super soft and stretchy slime.

Next, add 1 tablespoon of contact lens a little bit at a time. Add about half and mix throughly. Before adding the next half start kneading with your hands.

Keep kneading until the slime becomes less sticky. Remember the slime will be sticky at first, that is totally normal, keep kneading until the stickiness decreases.

Add 1/4 more contact solution if your slime is still sticky reduce the stickiness of the slime. Do not add too much contact lens solution as it will make your slime stiff and inflexible.

Remember you may not need to add the remaining 1/4 tablespoon of the contact lens solution so keep kneading before adding more contact solution.

You slime is ready when it has a firm, wet, slimy substance.

Make Your Slime Glow

Time to “charge” your slime! The best way to charge your slime is in the sun. Spread it out as much as possible so that as much surface area as possible can get charged.

It doesn’t take long to charge your slime. Let it sit in the sun for a few minutes and you will see the effects immediately. Using a bright indoor light is another great way to charge your slime at night.

How to Store Your Glow in the Dark Slime

Store your slime in an airtight container. It will last about a week. I like to store our slime in a ziplock Make sure to remove as much air as you can to ensure that the slime lasts as long as possible.

Age Suitability

This activity is great for kids 4 years and up. My kids are 4, 4, and 7 year old.
