This is something I've been experimenting with but figured y'all would like it, too. If you're like me and want to be slowly fed a fattening gainer shake while you game/relax/whatever, you've gotta try it. Simply put the tube in your mouth (like a straw), turn it on, and let the machine slowly feed you fattening gainer shake. 🤤 Assembling it is pretty fast and straightforward, but I would def recommend reading through all the instructions first.
I used a 1.5L bottle with a sturdy cap. The size of the bottle isn't super important as long as the cap can withstand the air pressure (explained below).
Pick your favorite calorie-rich liquid. I used Soylent, but Boost or melted ice cream would do great here. Just make sure it isn't too thick, as your pump may struggle to push it through the tubing.
The way this works is air is fed into the bottle, displacing your shake into the feeding tube (and then into your mouth.) So, you'll need an aquarium air pump. I used a small (and slow) pump from walmart, but I'd imagine one like this would be better. You'll also need quite a bit of tubing.
Now that you have all your supplies, start by washing your bottle & tubing. (Remember, you're eating out of this thing!)
Start by taking your clean bottle and poking two holes in the cap. Make sure they are perfectly round and slightly smaller than the diameter of the tubing to create a good seal. (this is the hardest part)
Then you'll need to cut your tubing. I cut my tubing to have about 6 feet (~2m) on the feeding side, and 2 feet (~3/4m) on the pump side. On the pump side, attach the check valve that came with your pump (it should have an arrow telling you which direction to attach it to the tube).
Then carefully feed the tubing through the holes you poked into the lid. Pull the pump tube about an inch through, and the feeding tube however far it needs to reach the bottom of your bottle.
(NOTE: due to the air pressure, there may be a rush of air through the feeding tube when the level of shake in the bottle goes below the end of the feeding tube. This also happens if the bottle is knocked/falls over. I didn't find it to be too intense, but please be mindful of this and use it safely!!!)
Then, fill your bottle with your shake and carefully feed the tube into the bottle as you put on the cap (again make sure the feeding tube touches the bottom). Screw the cap on so it is nice and secure.
Now attach the pump tube to your pump. (At this point I would strongly recommend testing your setup for leaks and making sure the flow of shake isn't too fast. Use common sense and be safe.)
5. Simply put the feeding hose in your mouth like a straw, turn on the pump, and let the magic happen.
Let me know if you have suggestions/questions, and enjoy!
