In celebration of the new Ghostbusters movie (we’re going to see it tonight!), I decided to try my hand at making some iconic Ghostbusters slime for my little one to play with.
My #1 requirement for our slime was that it be edible (read: taste safe). As the little guy is currently 13 months old, he’s still actively putting things in his mouth, and most homemade slime recipes include rather unsafe to taste ingredients such as borax and/or liquid starch.
So, while doing a search for a safe-to-taste slime recipe, I came across this post from Little Bins for Little Hands. (They are an awesome resource for activities for little ones, btw, especially for STEAM. Be sure to check them out!). I loved the idea of using gelatin and corn syrup, as I knew it would be perfectly safe for ingestion. But I also wanted to to create a special “Ghostbusters” version of the slime. So I came up with the adaptation below.
The slime resulting from this recipe was super slimy! It was also super sticky and super slippery. (It actually rather resembled snot at first, which makes sense, as this slime originally started out as an adaptation of a fake snot recipe.) Hence, the super slimy-ness. (And grossness!)
That element, however, made it even more perfect as a “Ghostbuster’s Slime.” Based on the description given in Entertainment Weekly by the cast of the new movie, we think this version seems pretty darn close to what they used in filming!
First, though, if you’re intending to use this slime for messy play with your kiddos, just a few notes of caution:
1) Our version is not only edible, it is actually tasty and smells really yummy. (Yes, I sampled it just to see . . .) It is made with corn syrup, so it is also pretty much flavored sugar. Although our recipe is taste-safe, you probably don’t want to feed it to your baby/toddler as a snack. So, you definitely want to supervise this activity (which I’m sure you would do anyway 😉 ) to moderate the sugar consumption.
2) As mentioned, this slime is also super sticky. Great for messy play; not so great for mommy (or daddy) to clean up. I am a big believer in the benefits of messy play, but not such a big fan of clean-up. So I recommend doing this activity in a dry bathtub, so you can hose the little one off afterwards or, if you’re in a warm season or locale, outside in the kiddie pool.
Okay, so here’s our version:
1 6oz box of lime Jell-O
1/2 cup water
1/4 cup corn syrup
Heat the water in a microwave safe glass container (such as a large Pyrex measuring cup), until boiling. (About 1 minute.) Sprinkle the Jell-O on top of the water and stir until dissolved. Let sit for 1 minute, then add the corn syrup.
Note: According to the original recipe, you should immediately have a reaction and, “presto, change-o,” slime. However, I attempted this process no less than 10 different times (no joke!), using both unflavored Knox gelatin as well as a few different boxes of Jell-O, and I did not get this instant magic. A commentor on the original recipe also noted the same problem, so there might be some kind of difference with water types, maybe? I’m not really sure . . . I tried all kinds of different amounts of water and different amounts of corn syrup and never got anything but runny liquid.
But . . . there is an easy fix! Just give your Jell-O a little time to set up, just like you would if you were actually making Jell-O. I put ours in the fridge, and after about an hour, voila – we had slime!
The little guy and I played with our slime right then, but I reserved a little just to see what would happen over time. (If it would harden into actual Jell-O.) It did tighten up a little by the 3-hour mark (resembling jam), but if you sprinkle a bit of water on it and stir it in, it will loosen back up. I also checked it again this morning after it stayed in the fridge (in an air-tight container) all night, and it’s still slime! So if you make this ahead of time, it should last a bit for play later.
Note: I did stir it a few times during that first hour (in theory this was to break up clumps, although it was still clumpy), but I don’t know if that actually affected the solidifying process or not. (I had run out of gelatin to experiment with at that point!)
Little One was very happy with our one-hour slime, though. Here he is “discovering” this messy substance. Notice the slimy strand from his finger tip:
I put him in the highchair for this activity, but in retrospect – I definitely recommend the bathtub! As it was, he ended up there anyway . . . 🙂
Here’s another view of its gooey-ness:
I just love the green color the lime Jell-O gives this slime!
Although I originally intended this as a baby/toddler activity, this would also be great science learning for bigger kids and a fun movie tie-in activity for those kiddos old enough to enjoy the film. (It’s rated PG-13.)
If you try this activity, please let us know how it goes! Especially if you’re able to get “immediate” slime – let us know what worked/didn’t work for you. It’ll be like a group science experiment! Please reply in the comments section below.
