Introduction: Student Hacks: Sub Zero Any Drink in 60 Seconds With This Gadget
My inspiration for today's project was to invent a tool that could really help students cool off quickly, impress their friends and at the same time, have fun building it!
So i made it a goal to make sure i used parts that are totally relateable to the average student. Really, most of the parts in today's project are most likely to be found already lying on your table, if not just scattered 3 feet away from the desk!
Before you go and think this idea is crazy because "i could just add ice to my soda" it's actually meant to chill beverages that aren't so good when diluted with water from melting ice. say for example Beer, wine and most, if not all liquors.
Lewis did a really cool review about "the spin chill" on his channel, unbox therapy! (see his video above)
But first, let me explain the science behind how this "centrifugal chiller" works...
Traditionally, us students would submerge our drinks in an ice bath inside a cooler, typically it would take around 30 minutes to achieve that refreshing temperature we all love.
But this tool we're making today spins the liquid inside the can.
Why you ask? Because in contrast to a can normally submerged in ice, this device cycles all the liquids inside to be exposed to the can's surface which is submerged in ice water resulting in the warm liquid moving out from the center onto the surface of the can, Evenly cooling the whole contents of the beverage. Unlike the traditional way wherein only the outer surface is chilled and gradually reaches the warm core, it would take approximately 30 minutes, if not more to reach an ice cold temperature.. that's gonna take forever when you're thirsty!
Let me quote some great pointers made by great people from the comments section.
"The Motor has to have a RPM of 240RPM Minimum. This will chill a totally warm can to Super Cold in 2 Minutes. 240RPM is not much. so if its a faster RPM motor it would probably cool faster than that (Drill as motor). Less RPM needs more time." -locklarryup this kid is only 15 years old and came up with a well said explanation. i'm waiting to see your first project okay! :)
"Awesome idea! You've got about a quarter of the story as to why this works. The first bit, like you said, is that rotating the can continually exposes "new" fluid to the inside surface of the can, making heat transfer into the ice water more efficiently. In addition to this, the same is happening with the ice water on the outside of the can, exposing "new" cold water to the outside surface." -Radioactive_Legos Yo. you guys have to see lego's page. he has a very deep knowledge in a wide selection of topics based on his very informative comment, i hope to hear more from you soon lego, great advice!
Essentially, we're fast forwarding 30 minutes into just 60 seconds!
And NO. the drink will not explode once you open it because the drink isn't being shaken, it's stirred! So sorry James Bond, this project is definitely not for you.
I entered this project in the dorm hacks contest! If you want to support me, your vote would mean a lot to the channel's improvement!
I try my best to always improve and challenge my DIY and film making skills so i try to find ways to afford better equipment. The macbook would be more than enough to push the channel's quality, it would be a huge leap for releasing some new cool and interesting projects i have in stock for you guys.
Anyway. If you had fun with today's project and you think it could play a big role in your exciting college experience, go ahead. Favorite and Share the tutorial to the closest person you think would enjoy a nice and easy DIY hack today, they'll love it!

Step 1: Grab These Stuff From Your Drawer!
Okay maybe some of them you'll find ON your drawer, but anyway.
Here are the 9 Supplies we'll need to chill your drink!
- A hot glue gun
- Permanent marker
- Plastic ruler
- Pair of scissors
- A lighter
- A motor (From a cheap remote controlled car!) The one i used in this tutorial, i had lying around from my previous robotics competitions (https://www.pololu.com/category/51/pololu-metal-gearmotors)
- A spray paint cap
- Old Usb cord
- A warm canned soda of your choice
(optional: you can add some table salt to the ice bath to chill the drinks around 40% faster!)
This is a 15 minute build, take it easy guys!
Step 2: Measuring the Cap
Okay, this is very simple guys.
Measure 3 cm from the bottom of the cap and mark it with your permanent marker,
Then cut off the marked surface afterwards, make sure it's as straight as possible!
Step 3: Heat Forming the Plastic
Who knew the paths of sticking a lighter to plastic would someday cross
As intimidating as it sounds, it's actually a really cool skill you'll find really useful in the future.
Go ahead and mark the plastic where the lip of the soda can ends with your marker, a good tip is to light it up with your cellphones' flashlight and mark it with a marker.
Spark up your lighter and gradually heat the sides until it starts to sag, that's the time you'll know its ready to be shaped! Don't make the same mistake as to heating it up for too long or it would just melt some holes. it wouldn't look so nice if that happened. Press and roll the edge of the scissor against the softened plastic and it will instantly cool off and take the shape of the can's lip!
As you can see on the last photo, there are marks wherein the plastic cap clips tightly to the can. that's what we want to achieve!
Step 4: Mounting Your Motor and Some Elementary Electronics!
As you might notice, i covered the plastic cap with electrical tape to cover the overheated parts, it didn't look so pretty so i covered it instead. rest assured it sticks to the can, no tape needed.
Mount the motor to the plastic cap first by marking the center with a marker, fix it with a generous blob of hot glue!
Grab your old usb cable and cut off the charging end. in my case, mine was a micro USB cord! strip the red and black wires and solder them directly to the motor, optionally you could add a switch for better control!
Step 5: Mounting It All on a Ruler
I looked hard around my room for something i assumed every student had lying around to use for mounting all the parts of... and it was right in front of me, It was the poor ruler!
Take your ruler and mark it where you'll need some holes to be drilled with a marker, once it's set. drill a hole with a pair of scissors by wiggling it back and fourth till' it forms the ideal sized hole! Fix it in place with the screws it came with afterwards!
(Alternatively:If the motor you're using didn't have a mount like mine did, you could just fix it with a blob of hot glue and you're all set!)
Ideally i designed this to be usb powered so you could plug it on any usb port to chill your drink anywhere you go, let's say with your trusty power bank as a power source! I took the opportunity to use this perfect sized one i had lying around for this project.
Mount it on the ruler with a dab of hot glue and firmly press it in place.
I added a switch as you could see on the last photo, it's totally optional!
Step 6: So How Do I Use the Cooler?
As you probably have asked yourselves "but can't i just add ice to my drinks and it will be cooled off?"
Well that's not the point of this project, this was actually designed to chill beverages people would normally prefer to not be diluted with the melting ice water, say for example: Fruit juices, Beer, Wine, Milk, liquor.
Will the can explode on my face? nope, i guarantee, you're totally safe. the device spins the liquid around without disturbing any of the carbonation inside, thus no pressure is getting built up.
Grab a cup full of ice cubes and submerge it in water in a nice bowl where your beverage could be comfortably submerged in the ice bath. Optionally you could sprinkle a tablespoon of salt to the ice bath to speed up the process by 40%
Start a timer for 1-2 minutes depending on how cool you'd like your beverage to be and just let the device sit on the lip of the bowl and let it do all the spinning!
I hope you enjoyed today's project. I'd love to see your very own version of the rapid drink chiller because who knows? I might have missed a brilliant idea that you probably could have figured out!
send me pictures and feel free to ask any questions, i'll typically reply to you within a few hours guys.
