For our Fall Festival this past year, we used Group’s Slime Time Fall Fest. In my opinion, Slime Time is one of the best Fall Fest curricula ever written. It is now out of print, but we have used it for the past few years because the kids loved it so much.

We decided to make a Nickelodeon-style Slime Tank to place on our main stage and have “Slime Times” every 30 minutes throughout the event, where someone from our children’s ministry staff stepped into the tank to be “slimed.”

A child (who you will see on the opposite side of the tank in the video below) turned the handle on a crank that was attached to a barrel of slime. The slime traveled up a clear tube, over the tank, and would come out on top of the head of the person sitting in a chair inside the tank.

Here is a brief video of us using the tank during the festival.

You can build this same tank for about $200, plus the cost of slime. The nice part about this tank though is the most expensive features are reusable so it’s mostly a one-time cost.

Here’s what our construction looked like, in process (click the image to make it larger).Slime Tank

Here are general and specific materials you will need and costs of specific materials (at time of posting):

  1. 15 gallon “Natural” plastic drum– $41 (reusable)
  2. Rotary drum pump– $99 (reusable)
  3. Green inflatable pool– $33.95 (potentially reusable, easier to discard)
  4. Clear rubber tubing for drum pump (potentially reusable, easier to discard– cut to length you desire)
  5. PVC pipes and connectors (reusable– cut to size you desire)
  6. Clear shower curtains (recommended to cover all sides)
  7. Duct tape (to hold everything in place, use lime green to make it more fun).

You’ll notice from the photo above that we put the clear tube through the PVC going across the top and cut a hole in the middle of it and fed the tube back out of it. This worked well, but I’m sure there other ways of doing it. Feel free to experiment.

After you finish using the tank, all of the really messy parts (pool, shower curtains, and tubing) can be thrown away. You will only need to wash out the drum and the pump, if you want to keep them to reuse. Reorder the disposable supplies for use later.

For the slime recipe, you will find there are many options available if you perform an online search. The easiest and least messy clean-up recipe we have found is simply apple sauce and green food-coloring. We made it a bit thinner by adding some water. This helped it flow easily through the pump and tubing. I should also say the food-coloring has never stained our skin or hair, but everyone showered as soon as they were slimed. A word of caution– if you use apple sauce, be sure to put an old rug, carpet, or something with texture in the bottom of the pool because the apple sauce makes the pool surface extremely slippery, even with shoes.

I hope you have fun with this idea in your ministry! If you have any questions, leave them in the comments, and I will answer every one that I am able.
