#1 that fridge is more than just a fan, it's a thermoelectric plate. When you run a current through it, one side gets cold, the other side gets hot. So the fan is to vent off the waste heat, while the cold side of the plate chills the beverage from below. I used to have a six-can version on my desk back when I was in the office. I'd keep a couple cases of soda under my desk, then at the end of the day fill the mini fridge back up. By morning, I'd have six well-chilled cans ready to go. Now though I work from home so if I want a drink I just go to the kitchen and get one lol
There are molds that are designed to make clear ice. They usually work by leaving the top less insulated. They heavily insulate the sides and bottom so the freezing happens uniformly top to bottom. They will also have an extra resevoir underneath the freezing section to help separate it because the ice at the bottom of this setup will never freeze clear
@@crisppzanuff4398 I tried with hot water and it seems slightly better, although the big difference is always how well insulated the mold is on the sides and bottom
Clear ice makers are a thing, but they are very expensive. Usually used in bars for drinks. Clear ice actually melts far slower than cloudy ice, which makes it good for drinks. It also takes a very long time to cool.
Actually, I found one that works well for around $18. Only 1 ball though. It works great by itself, but it recommends a styrofoam box for best results. Personally, haven't needed one. I'm testing other ones at the moment too.
I had one of those usb mini fridges . I added some insulation from and old lunch kit and cut to fit all sides and top of the inside of the unit . Made a big difference . Also it works best at keeping an already cold drink cold , not to cool a warm drink down .
@@flyingtanks9313 I forgot the name of that component but it's like a solid state plate that displaces heat, making one side cold and the other side hot. It has a fan (and also appears to have a radiator) to remove the heat. Edit: It's called a peltier.
It would also benefit from 10 volts instead of the measly 5 volts they are using from the USB. Most Peltier devices are ran between 8 to 11 volts. Lower voltages will give you a better efficiency of heat transfer from the hot side of the peltier but the low voltage means the cold side will never go very low. Most portable car fridges run on 12v, but those have more robust heat dissipation systems to get rid of the waste heat. Id say if this was ran on 10 volts and was given even just a bare amount of insulation it could easily chill a can down to 45F. However one further improvement that could be made would be a bottom plate that is shaped to slot into the concave bottom of the soda can to give maximum contact between the two.
The mini fridge basically works by using a thermoelectric Peltier device that the cold side is facing the bottom metal plate inside and the hot side is where the heat sink is attached to with the fan blowing on it so it’s not hot
That coke can fridge is really cute, quite a novelty to give someone in your office for a gift. My favorite of all was the simple Ice cube and ice ball molds. Those balls and cubes do not melt as fast as other cubes and will keep your drink cold much longer, not to mention how COOL they look. That ice shaver would be great for those with small kids who want a cold popcicle in the summer. Another great video Dave.
sad part. in sweden thoes chungus can don´t exist anymore here. every can is like a long small redbull size can here nowdays. so i dunno if it will fit anymore. atleast it would be barely.

@@yashika-singh For home use that seems like it would work. But, if you need more of it, the trick is to keep the water moving so that the air bubbles and impurities aren't trapped. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pLekp8HajkA.html If you had an extreme amount of patience, you could probably also create thin layers of black ice by adding extremely thing layers of ice which are so thin that they don't trap air. But, that would take far longer and require more complicated tools.
I'm guessing the USB fridge uses a Peltier cooler-I've got a similar device on my desk right now which I picked up last year (though it's open, and has a little metal cup you can pour your drink into). A Peltier cooler works by passing electricity through two adjacent plates of different metal which causes one side to heat up (where the fan blows, to remove the heat) and the other side to cool down (where the drink goes). The difficult part is conducting the heat through the drink to the plate to be removed, which is why the top of the can was warmer than the bottom, though you could gently stir it to help. And the really cool bit is that it works better the less liquid there is, so the last sip of your drink can actually be colder than the first!
I've always wanted to be a chef and this man actually shows off useful items instead on telling me "this gadget made 3 people tried bathing in coke and that got rid of their cancer"
Use the same ice molds but put them into a small double walled cooler box with water surrounding the mold... Water freezes top down so if you want it to be clear make sure the mold can release the air downward
Wow! I liked the drinks recipes and am definitely going to get some of those gadgets and give them a try. The USB fridge was interesting, too. Many thanks for this vid!
You want clear ice, you need two things. First, use distilled water. Less impurity makes a clearer cube. Second, freeze the water slowly. Put your ice tray in a small styrofoam cooler then put it in the freezer. Might take more than just overnight but it should freeze remarkably clear.
For clear ice, you need to freeze the water slowly. I usually put the ice cube trays in a small portable cool box, and then put that in the fridge. It always works.
Boiling the water first helps, too, by removing some of the air dissolved in the water. That's the primary reason for cloudy ice, the dissolved air getting trapped in bubbles as the ice solidifies.
Dave you're one of the only person I could watch when I was 5 and still watch. You're channel hasn't changed at all thats why I am still a viewer, thanks!
I love how when he have gadgets that need more time to work, he shows them at the beggining and leave them on "for later". He could easily edit the video, but there's still that little feeling that we wait with him. :D
Hey Dave, it's been months but if you still wonder, to get clear ice, you ought to freeze it in multiple layers. Like you can place your mold into a cardboard and then put it in freezer.
Tipsy Bartender has a great video on how to make clear ice, and he actually recommends that you do NOT boil water, as all the clean water will evaporate and leave behind water with a higher concentration of impurities
I love those HUGE square and round large ice cubes! I like large cubes to cool off my lemonade without watering it down so fast!So I'll freeze some of my lemonade in them too.I can freeze ice cubes of any of my drinks ,like sweet tea.
I recommend using some bottled water if you want clear ice, not sure if it works with all brands mind you, but there's generally too many minerals and stuff in tap water which clouds up the ice, at least from my experiences... I see people mention boiling water first in the comments however, which I haven't tried before, but it may work aswell.
I have that mini ice crusher. In Malaysia, this food has been a favorite dessert for many years. This is the classic preparation method we do • Sprinkle on the ice with a few drops of condensed syrup then a few drops of palm sugar (pre-cooked and cooled first to prevent the ice from melting as you pour it) + condensed milk sprinkle on top + sprinkle some nuts on top.... Wallah! ✓ _Bon Appetite!_ 😋

You can also take a wet paper towel and wrap it around the beer bottle. Throw it in the freezer for 10-15 minutes (maybe even less) and you have a super chilled beverage.
