We've been using cake mix a lot and were wondering how to make it thicker we've heard oats work but do you make the oats first and mix them in or just dump dry oats in the mix, any other recipes are welcome too! Hoping to post more content here

All you gotta do for oats is boil water then once boiling add oats and stir for like 2 minutes? Then turn off heat it'll absorb the rest of the water then add to cake batter... Idk how to make it thicker other than less water/oil... It's all a process of trial and error everyone can give you their best recipe here but if it's not to your liking it might bug you... Also just wanna suggest corn syrup to thicken it

There are various ways to make good slime/gunge.

As TheWamdalorian says, it's all down to personal preference and a bit of trial and error.
Using less water on the oats would make it thicker.

One thing that I've done before is make your bucket of cake batter as normal, then spray in a good amount of shaving foam (or avalanche foam if you have it), and give it a good mix up. It goes lovely and creamy.

In our humble experience (and it's lengthy), you just cannot beat Tesco or Sainsburys smooth oats. Not normal porridge (nasty texture).... but the smooth stuff.

About £2.20 a box, but 2 boxes gives you a full to the brim builders bucket.

Amazingly gloopy and the texture is yours to decide. Just use hot water to mix.

Add a bit of veg/olive oil to make a bit slimier if you want. Food colouring to colour (mix that into the water first for best results).

Mix in a small tin of black treacle for the stickiest gloop ever.

We mix it in different bowls, making some very thick and some slimey.
Then tip them all in one bucket. You get a great gunging out of that with various textures.

Tara has had more than her fair share of 'Smooth porridge' in her time

Oh... and it dissolves down the drain or loo fine.

I use cream of wheat, milk, applesauce, jello powder, and green food coloring. The thickness just depends on how much milk (or water) you add. Just be sure to wash it off quickly because it's hard to get out of your hair once it dries on!

That sounds amazing... but anything that 'might' dry in your hair or contains milk (hence horrible sour smell later on) has always been a no-go for us.

Each to their own!

I just add the oats to a cake mix batter and add more water then mix thoroughly. I use a drill and mixer attachment. Add food coloring = done! The oats will still absorb the water by the time we get to film (about 1 hour later).

A very nice sticky, gooey slime can be made very cheaply with Arrowroot powder. (also called Arrowroot flour)

You fill a sauce pan with cold water, then stir in the arrowroot powder, probably a half cup to a full pot of water. Don't try mixing with warm or hot water, as it will be nearly impossible to dissolve.

Bring it near the boiling point, and stir with a wooden or plastic utensil. (so you don't scratch your pot)

As it gets hotter, it will begin to show steam rising and then suddenly it will go transparent and turn thick. Stir a bit more, leave on heat for about a minute, then turn off burner.

I like to have the sink prepared with the right level of cold water, so I can just set the pot in the water, being careful none leaks in. Stir once in awhile so the hot stuff in the middle gets to the outside of the pan where the heat will be drawn out by the cold water surrounding the pan.

You will notice it thickening as it cools. If it is too thick, now is the time to add water and stir it in. Once you're happy with the result, make SURE it has cooled to a safe temperature, then enjoy.

When you begin this process, you can add tempura paint to the water, or food coloring, to give your slime the color you may want.

So for those who hate reading and can't remember shit, here is the short version:

1. put cold water in a pot and stir in some arrowroot flour
2. put pot on stove, heat on high while stirring.
3. when it steams a little and turns thick, remove from heat

On my profile, I have a short video on making this slime. Take a look.

Simple gunge mis 100g of xanthan gum with cooking oil until you have a stirrable mixture in the bottom of a bowl. Using an emersion blender stir colored water, you choose the colouring, and pour the xanthan into the blender blades. In about 5 minutes you have slime (xanthan is a pantry item btw).

Add corn starch or cake batter to make more opaque. Add chunks if food if you want chunky slime.
