Hi all! This coming Friday night, I have a big pie and slime session planned, with my wife set to throw 40 pies at me and a few slime dumps. For the longest time though, I've been trying to figure out how to get a perpetual sliming. I'm not quite there yet, but I do have one of those big 5-gallon buckets and I've drilled a hole in the bottom and I have the apparatus ready to have it suspended above where I'll be sitting.

But I need help with the release mechanism! I'm not tech savvy so there's no way I get this set up with a remote controlled valve anytime soon. I need ideas on how to get the slime to start falling through the hole at the bottom.

My usual hands-free slimings is just a double lined grocery plastic bag with three boxes' worth of cake batter slime in there. I suspend the bag using coat hangers and then just pop the bottom of the bag open with a butter knife or screwdriver. Images below of what that has looked like in the past for me.

But with about 5 times that amount going in this bucket, I needed something better than just a plastic bag. I've experimented with water only a couple times earlier this week where I lined the bucket with a standard trash bag and pulled a tiny corner of the bag through the hole before I started filling it. And then I just snipped off the corner to start the flow. But this is going to be high above me and I'm not going to be able to simply reach up and get it popped. I need some kind of membrane covering the hole or some kind of plug I can just pull out with a string or something.

If anyone here has had luck with different designs, I'm all ears. Thanks I'm advance!

Buy a bath plughole and plug from Home Depot, fit in bottom of bucket. Attach a cord to the plug and lead it up and over the side to hang down to where you are sitting. To release the gunge, pull the cord.

Please be careful and think about this. 5 gallons of slime is going to weigh over 40lbs. Be sure to have sufficient support for this - simply suspending it from the ceiling is unlikely to cut it as it will be unstable and prone to movement.
That aside, the cork idea mentioned above is a possible option. Another idea might be to use a balloon as the membrane and tape it in place with something like duct tape. Then pop the balloon when you're ready to release the slime

I plan on doing this session in my garage and we have an attic access that I will open up. Like I said, I tested it with water earlier this week and I did it by putting two 2x4's across the attic opening and set the bucket on the boards with the hole positioned to be in between the two 2x4's. The weight isn't really the issue. It's more that I had to put it high up in the attic to support the weight and now it's harder to reach the bucket to pop open the bottom.

I'll look into the bath plug options available at Home Depot and see what might work.

I have a tendency to over-engineer stuff but hear is how I went about solving a similar problem. Turns out you can get rubber bungs for test tubes in a variety of sizes and you can get them with a hole drilled out through the middle. Bought the biggest one of those I could get hold of (~42mm if memory serves, about 5 quid off of ebay in the UK), a cheap hole saw drill bit, a nut and bolt with an eyelet in the end slightly larger than the hole and I already had a couple of repair washers. Sandwiched the bung between two washers sent the bolt through the lot and tightened the nut up nice and tight.

If you're going to be pulling from underneath, tie a second rope/string off to the side of the bung, so it swings away rather than relying on a catch to stop it hitting you in the head. Better design is to have some kind of pulley and a longer string so you can pull it out from above, but you'll also need some kind of counter weight to make sure it doesn't just rest back in the hole in your bucket.

Found a bit of a throw away picture from underneath our tank, which I've added.

That's kind of the idea I have in mind. I just want to ensure it creates a tight enough seal that it won't be leaking and dripping before I'm ready for the slime.

We used the flush mechanism from a toilet.

Here's a different sort of idea, I'm an engineer but will try and keep this as short and concise as possible. It's a design I have the supplies for but haven't assembled yet.

For the tank, get a 5 gallon office water cooler bottle. It will be mounted the same orientation it is when being used as an actual water jug (flat part on top / cone-shaped opening on the bottom). Cut a hole ~4 inches in diameter on the flat side that you can use to fill it with / will let air in as it drains. To connect pipe to the jug you will need a 2" Fernco

a length of 2" PVC, and a 2" PVC quarter turn shutoff valve

You will need to fit a stick/rod/whatever to the valve for leverage when you open it, and a string to pull with since it will be in the air above you. Also a piece of plywood with an opening in it for the jug to sit in while serving as a tank (I also recommend a frame made from small pieces of lumber to prevent the jug from being able to be tipped over).

Science content: the reason I went with a jug rather than a bucket is for it to be able to better maintain flow rate as it empties. Think of the shape a water tower is in, they aren't cylindrical as that shape is less efficient. A water (gunge) column is what provides pressure.

Damn that's smart.

This sounds very similar to a beer bong setup my buddies made in college. Huge reservoir at the top, long clear hose coming out of it clamped in place, and a 1/4 turn valve to control the flow. Get on your knees, tube in your mouth, turn the valve and chug. Most I ever did was two beers at once. Lol

UGH better you than me I have roughly zero alcohol tolerance and I have no idea how people are able to just pour beer straight down without the foam and everything else coming right back up the top!

I've often day dreamed about this, just don't have the space to build the apparatus at this time.

Got a slightly better picture at the weekend before we filled the tank up.

The seal is usually pretty good if bung and box have been cleaned and dried. The tape is there partly to allow for any imperfections in the hole. It's about 4 or 5 layers. If we've done a few scenes back to back, there have been leaks, but only usually if we've been careless in cleaning up. And we're talking one drip every 10 seconds kind of levels.
