How to Make Green Slime: Perfect for a Messy-Themed Party

By Rachel Tiemeyer

I’ve got green slime on the brain…and probably still in my hair.How to make green slime

Last week, the team I work with was in charge of our 11th year of what we call Kids Club at our church. It’s kind of like VBS on steroids. I’m 33 and it makes me feel like I’m 18 again. There’s really nothing like it that I’ve experienced—one week where 900 people of all ages come together to have fun, build relationships, and learn about Jesus in a completely unique way.

Anyway, this year, our theme was “Go for Gold!” and all about the Summer Olympics. Each night we had an Olympic challenge on stage, and the kid or adult who lost had to enter our Slime Tank (Double Dare anyone?).

I’m telling you right now that you can’t go wrong with green slime and a Slime Tank. Kids asked me every night if they could go in the slime tank and/or I could give them the green slime recipe. Needless to say, there was always a huge crowd reaction when someone got slimed.

One of the last nights, I was subjected to this ultimate punishment…

Ironically, Polly‘s husband was also in the Slime Tank since he was one of the main skit characters…

Here’s one last peek into the slime tank before I reveal our secret recipe for the next time you have a messy-themed birthday party, or VBS, or decide to set up your own slime tank! I think everyone needs one, really.

How to Make Homemade Green Slime


  • 6 packages green Jello powder
  • 1 gallon water, plus more as needed
  • 10 lbs of flour (two 5 lb bags)
  • 1 large bottle of baby shampoo
  • 1 large bottle of green food coloring
  • Optional: boogers, toe jam, or belly button lint


  1. Mix the Jello packages and one 5 lb bag of flour and about 1 gallon of water with a large whisk or electric beaters. Mix well until most of the lumps are out.
  2. Add the other bag of flour in small increments and mix.
  3. Slowly add water to the remaining flour mixture in order to keep slime from being lumpy. Add as much water as needed until the slime is the consistency you desire.
  4. Once the slime reaches the consistency you desire, add 1/2 a bottle of baby shampoo and food coloring until slime is the perfect shade of green.
  5. Slime away!

    For the water , flour & food coloring recipe do you use the same amount of those ingredients as the other slime recipe ?

  2. Maria says:

    How far in advance can we make the slime? Would we have to make it the night before the event?? Does it dry out if made a few days before??

    • Rachel says:

      It’s been a while since we made this recipe, but we have just been using flour, water, and food coloring for our slime for the past few years. It lasts all week long at our VBS! Just cover it well with plastic wrap. Hope that helps!

    Our church will be doing a skit about Jonah and I will be vomited out of the whale. I am looking for a recipe that would represent whale digestive juices. Any suggestions?

    Fortunately, I had a chance to attend a messy-themed kids camp in summer where we were using shaving cream pies. We even had an “armory” full of pies 🙂 It can be easily removed from clothes and hair. It isn’t a big problem, if you don’t wash it out of your hair right away (clothes maybe) as it happened to me. Try shaving cream out.
    Once I got surrounded by little kids holding pies, I knelt down and let them pie me. I couldn’t wash my hair due to a burst pipe. (I totally forgot about bottled water) So I had been wearing a creamy hair for at least 12 hours before I washed it. It felt like bulletproof, but was easily washed out. Moreover, the kids started calling me Finn (from Adventure Time). A cute little girl even sent a letter why they did with an undisputed explanation 😀

    Try putting a little vasilene in everyone’s hair so slime will not adhere so readily. Also, suggest to people to wear old clothes if they are being slimed.

    We used this slime recipe for our “Messy Mess Day” in our township and had a great time! The kids loved it, however it was a hot, sunny day and the slime dried very quickly. We did have many complaints about parents trying to get slime out of children’s hair. The coordinators also struggled to get the dry slime out of their own hair. Some of the ways that they did get the slime out of their hair was with vegetable oil, vinegar, A LOT of conditioner (brush it out while the conditioner is in the hair), in case anyone else has this problem. The slime was a huge hit but my recommendation would be to not get it in people’s hair, and wear clothes that can be thrown out afterwards.

    • Rachel says:

      I totally agree, Shannon. Thank you for leaving this comment, as we have the same problem year after year. We are going to try to cover kids’ hair and clothes better when we use it. Appreciate the feedback!

    • Rachel says:

      That’s a great question. I haven’t made it in years unfortunately! And let me just add an update: The past few years we have simply combined flour, water, and food coloring for a simpler version.

    Hey, we’re using slime as a fundraiser, wanted to know how to clean it up. Say outside we dump it on ourselves, how to clean it up. Thanks

    • Rachel says:

      It was messy for sure. You have to wash it out right away. Water did the trick. But, do not let it dry in your hair or on your clothes if you can help it.

  8. Kristin says:

    Thanks for sharing. We are doing a challenge for missions and the boys or girls how raise the most will get to slime the other. What size baby shampoo bottle. Thanks!!

    Any other tips?

    • Rachel says:

      What a great idea! It’s been quite a while since I made the slime, but I think it was just a standard sized bottle of baby shampoo from the dollar store. I hope that helps.

    • Rachel says:

      I didn’t have a problem getting it off my clothes or out of my hair with soap and water, but the sooner you get to it the easier it is. We also got some on the carpet at church. Most of it came out, even though it had dried. But, the green dye could stain a lighter colored carpet I’m sure.
