Spin Chill was created because warm beer sucks and waiting for one to cool down takes too long. We both have Mechanical Engineering backgrounds from the University of Florida. This summer, an accelerator program called HackerHouse took us to Atlanta to participate in the AngelHack hackathon. The night before in our hotel room, we impatiently spun our warm beer in ice to cool it as we had many times before. Being in an inventive mood, we wondered if we could make a device that would spin the beer for us.
The initial prototype was hacked together at the competition the next day from a power drill, a baby bottle, and a roll or two of duct tape (Picture shown below with newer Beerouette designs). It took second place. We refined the idea by 3D printing multiple iterations of the design. In order to improve the clipping mechanism we simplified the device and created the Chill Bit which incorporates the same clip, but uses a power drill to spin the beer. Chill Bits were made by overmolding liquid plastic onto metal drill bits using 3D printed molds.
After demonstrating the Chill Bit and using it with friends we had tons of feedback from people wanting a self-contained device. That lead us to create the Beerouette. The pictures below and in the video are of an early version we created with a 3-D printed body and clip made from a rubber that was poured into 3-D printed molds, like the Chill Bit.
The first product that we created was the Chill Bit:
The Chill Bit has a standard 1/4" power hex bit that fits into the end of a power drill and a clip that clips onto the top of a can of beer or soda. There are also Chill Bits that fit bottles. The Chill Bit prototypes have been made from 3D printed molds and a 2-part liquid rubber overmolded onto a power-bit.
The next product we created was the Beerouette:
The Beerouette is a hands free, portable device that is completely self-contained with a motor, batteries, and a switch. It was designed to fit into a pocket and be easy to handle and carry. The clips for the prototypes were created the same way as the Chill Bits and the bodies of the Beerouettes were 3D printed and screwed together.
It typically takes 20-30 minutes for a warm can of beer to chill down in the freezer, 10-20 minutes in ice water and 30-60 seconds by spinning it with the Chill Bit or Beerouette. Bottles take a little longer because glass is a good insulator compared to metal cans.
By spinning the container, you are introducing convection to both the inside and outside of the container and increasing the surface area in contact with ice, increasing the rate of heat transfer by a minimum of 20 times faster.
The container does not explode when opened: it foams even less than one that is chilled down normally. To understand we have to explain why something foams in the first place.
A liquid foams when micro-bubbles built up around the inside of the container release into the liquid. The contents inside bottles and cans are pressurized so when they are opened the bubbles shoot through solution to the surface to equalize pressure. However, spinning the container pulls all the micro-bubbles away from the walls of the container to form one large bubble at the top of the container. Now when the container is opened the bubbles don't have to go through the liquid to equalize which results in less foam.
Since ice water is always 32 degrees Fahrenheit, Spin Chill can only chill a beer to 32 degrees in ice water. However, ice that hasn't melted yet is below freezing so Spin Chilling in fresh ice can get a beer colder than 32 degrees and create a beer slushy. Get your beer as cold as you want!

Risks and challenges
The largest up-front cost of manufacturing is having aluminum molds made for injection molding. Molds are the largest cost risk because if they are made incorrectly then they have to be remade from scratch which would take both more time and money. However, we have been working with manufacturers to ensure the parts are designed correctly and will be optimal for injection molding in their machines. We have two manufacturers, one who will be making the bodies for the Beerouette and the other who will be making the clips for the Beerouette and making the Chill Bits.
One of the biggest potential challenges after the parts are completed are the logistics of getting everything fully assembled and to your doorstep. Since the Beerouettes are being assembled in Gainesville, FL, we have been working with our two manufacturers to ensure that they will be able to deliver the products to us in time to assemble them and ship them. We have already setup a scheduled timeline with them to alleviate any uncertainty and have built in a buffer to account for possible problems that may occur due to shipping.
As soon as the goal is reached our manufacturers are going to start production. This will keep the lag time, from when you back us to the time you get your reward, as short as possible. Projected delivery times are listed under each reward to the right.Learn about accountability on Kickstarter
