Hey all,

I work with a lot of models remotely, and was thinking about sending instructions for models to build gunge/slime tanks out of stuff from Home Depot! I'm sure some of you have experimented with this so I thought I would crowdsource the engineering.

What I'm looking for is a contraption where we can pour in the (chunky) slime ahead of time, and have a model pull a string to release the slime onto her from above at a relatively smooth/slow pace.

If anyone has ideas or a sweet design in place I'm all ears

I think you're thinking with the wrong head.

FYI my undergrad is in Mechanical Engineering and I've worked on consumer products like a guitar stand and a ball launching machine. I've also done some robotics and the like.

Asking models to essentially fabricate a gunge device for a single use in a scene will likely be prohibitively expensive since your paying for all the time to source parts and construct it by a non expert, and each time you lose whatever they learned in tbe process. Even assuming you are a multimillionaire doing this for fun and have an infinite supply of money, it still seems really unlikely you'll get anything out of it since the construction process and materials would vary.

I suppose if you had to do it, you could create a "Kit" yourself that assembles into a gunge tank, and then ship the disassembled kit to the model. That takes out making the model source the parts. Then they assemble it, do the thing, clean, and disassemble, and ship back to you.

But designing and creating the kit, I would still think of as pretty complicated. Maybe like give 3 engineering undergrads a week full time to design, prototype, test, iterate and finalize a kit that could be easily assembled and disassembled by your least competent model.

You could maybe fake it and have them pull a string and someone off screen dunps it or something?

This one's been around several times before. Try searching the forums for the word "mechanism" & you'll find most of the posts.

Remember gunge is heavy, suspending that safely above someone's head us not an easy task.
Asking someone with not much experience in constructing things (assumed, but they might be an expert I don't know) is jus asking for trouble.

This. ^^^^

The consequences if someone misjudged the loads and forces involved could be fatal, or leave the would be model with life-changing injuries - think paralysed from the neck down if a loaded tank falls on them from above. Do you have insurance that would cover those kind of medical bills? You'd be liable as you'd asked them to do it.

Only safe way to do gunge tanks is to have it constructed by someone who knows what they're doing and has at least a basic grasp of structural engineering / building work, and then tested multiple times for safety before risking a fragile human in it.

DungeonMasterOne is ABSOLUTELY correct. As is Scroogle.

You might want to start with a field sink which is safer because the slime would not be suspended over the model. It might only support watery liquid, though. Have a look: https://www.instructables.com/Field-Sink/

But for safety purposes, always test it on a beach ball first.

I found a pic of one Steve made for someone a while back now. He gets asked all the time.
This one obviously still has the plastic over the clear side panels

I believe (he isn't here at the moment), that this one was lightweight and folded totally flat.

He did offer to make them (and the release mechanisms), but people don't realise how expensive they can be. AND... They need to be safe.

More of a basic frame than a tank. Could easily enclose it with some polycarbonate sheets.
( FYI - polycarbonate > perspex. Just something I learned from covid. )

Upgrade the racking & you can support several hundred pounds per shelf.
Go for a heavy duty unit with re-enforced welded & powder-coated mesh shelves.
Easier to just align the nozzle through a gap in the mesh than drill through ( and possibly weaken some MDF sheet. )

Most are boltless so go together and apart without tools, usually in minutes.

Wow! that's a seriously cool piece of kit, i wish i had the space for something like that.

If you've ever lifted just a bucket of gunge, imagine that full bucket being dropped on your head, from a height.

1 litre of water is 1 Kilogram. A builders bucket, filled to just under the top therefore is around 12-14 Kilograms.

Mixing in substances to thicken it will reduce weight slightly.

1x full bucket of porridge/slime, dropped from a few feet will crack your skull, seriously compress your spine, or break your neck

Misses your head? Then the plastic edge of the bucket will happily remove your ear or literally carve your nose off.

If you build something.... make it safe. If you can't hang on the frame, then it's probably not good enough to support any decent quantity of goo.

I highly doubt you want to be found unconscious/dead, lying naked in a pool of brownie batter

Just be careful

I've made a simple homemade gunge tank a few times.
As in bucket with hole, and a plug attached to a string. Suspended above the bath tub.
Works well for a moderate gunging- but you won't get the epic full coating like with a full size tank.

Regarding safety- I had two individual 'strings' in a V shape holding the bucket, so if one snaps the bucket would swing to the side instead of dropping on me.
(safety by accident mind, I needed the V shape to put the bucket in the correct position).


An alternative would be to use a pond pump and hose to deliver the gunge.
(ideally battery operated so you're not using mains electric in the bathroom)
