Self Freezing Coca-Cola (The trick that works on any soda!) (03:18)

The King of Random · 4 years ago
Take any bottle of soda, and get it to freeze on command! This “super cool" trick works with cans of soda as well. Some quick links to a few of the materials I used: [✓] Coke: http://amzn.to/2cjDmmt [✓] Quaich (little silver dish from Scotland) :http://amzn.to/2cGNxy3 To date, I haven't seen any tutorials on exactly how to get this "self-freezing coke" effect, so I'm excited to release this video in response to thousands of viewer requests.

Glass bottles are not recommended, as the ice expands when freezing and can shatter the glass explosively. Use of video content is at own risk. Music By: http://www.MachinimaSound.com (Remember The Dreams) Project Inspired By: The viral YouTube video: "How to Chill A Coke In just a second!!" (http://youtu.be/ngt74e1DxPU) and the process of nucleation was inspired by "Self-Freezing Coke - Crazy from Kong!" http://youtu.be/j07SweYJTSM. Project History & More Info: I knew water could be turned to instant ice (http://youtu.be/sQdLttUh_b0), but was amazed to see that soda could be supercooled as well. The anomaly of "self freezing soda" has been observed by many people, usually by accident. Some people put a soda in the freezer to chill it, but then forget about it. When they've remembered and gone to get it, it's liquid until they open it, leaving them puzzled. Some people have noticed the effect by leaving the soda outside in cold temperatures. There is a vending machine in Hong Kong that sells supercooled Coke bottles, and the instructions to trigger nucleation is the same as in this video, however they recommend taking a sip when the cap is on. I believe this is to increase the chances of impurities being introduced into the liquid, making nucleation more likely. From what I've seen, the results in this experiment form an even thicker slush than the vending machine in Hong Kong. To get this effect, I put 4 bottles of 500mL (16.9 oz) soda in a freezer set at -24ºC (-11ºF) between 3:15- 4:00 hours. The longer they are in, the more dramatic and solid the slushy freeze will be. However, anytime after 3:15 hours there is a chance of them freezing before you take them out. Every freezer will be a little different temperature, and I've noticed the location of your bottles in the freezer makes a dramatic difference on freeze times. For best results, choose one consistent location in your freezer, and play around with freeze times to see what works best for you. In my freezer, the middle of the center rack settles at -24ºC (-11ºF) and takes 3:15 to super chill 4 bottles. Remember that the longer the freezer door is open, the more cold air will escape, and it will make your freeze times take much longer because your freezer has to cool down again. I've also noticed that the more frozen items you have in your freezer, the faster your soda will chill. In contrast, the less items in your freezer, the longer your soda will take to cool. Bottom line is, use a consistent environment for your experiments, and you'll get consistent results! I also experimented with 2 litter bottles, and had great results between 4-5 hours. The whole bottle slushifies in an instant. I experimented with Gatorade, Fresca, Mexican Sprite, Rootbeer, Orange sodas, Coke, Diet Coke, in bottle form, as well as in cans. I had super cooled success with them all! The trick to getting the 3 second slush, is quickly releasing the pressure in the bottle and re-securing the cap, flipping the bottle upside down, and back upright again. This is because the forming ice crystals will be moved around the length of the bottle, and trigger nucleation for the rest of the soda. If you were to just take the cap off, ice will form, and it will slowly spread downward, but might take upwards of 2 minutes for the bottle to completely freeze. Removing the pressure very slowly from the bottle, can keep the soda liquified, and give you the choice opportunity to play with supercooled soda outside of the bottle.

Music by: TheFatRat ("Xenogenesis”) Licenced by Tasty http://youtube.com/tasty Project Inspired By: Mikey77's Instructable on Ooogoo: http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/ Project History & More Info: Casting silicone is very expensive, so over the years I tried to find a cheaper alternative to making LEGO candy molds (https://goo.gl/XcLbep). I started off trying silicone caulk from the hardware store, but globs of it would take weeks and weeks to finally firm up. That wasn't acceptable because I needed something that would harden in 24 hours or less. About 3 years ago I came across an Instructable by Mikey77 showing that mixing corn starch into the silicone caulk could be used to make it firm up in under an hour. I did a number of experiments of my own, and eventually found out that corn starch wasn't actually needed at all, but that all you needed was to add a little food coloring. I still like to use corn starch though because it helps prevent the caulk from sticking to my hands as I work with it. The stuff is really hard to get off if it sticks to skin!

How To Make LEGO Gummy Candy! (06:19)

Music By: Scott & Brendo “Somewhere” http://bit.ly/ScottBrendoiTunes See their YouTube page: http://bit.ly/YTScottDW Project Inspired By: SFHandyman's Instructable article: http://bit.ly/IBSFHandyman Project History & More Info: Who doesn't love gummy candy, and who doesn't love LEGO? 5 years ago I was fascinated with it, wondering how it was made, and what gave it its gummy texture. It feels so good on the teeth to bite into it, and my kids go crazy for them .. so I spent a bit of time researching how they're made commercially. My biggest motivation for doing this was to see if we could make our own at home, and I'm actually still trying to figure out how to make gelatin and corn syrup from scratch, so if I can figure out how to do that, maybe I'll show how to do it in another project video. Only a small handful of you have ever seen the LEGO Gummy video I made in 2010, and that's because it was nearly 5 years ago, before I really got serious about making videos. I took it off my channel in 2012 because I had full intentions of making a better version, so here it is .. 3 years later! :) Now I wanted to make candies that made people look twice, and LEGO bricks instantly came to mind because what's more awesome than LEGO and gummy put together? But I wasn't sure where could you get a mold for making LEGO bricks. Surfing around the internet, I stumbled across an awesome Instructable by SFHandyman: http://bit.ly/IBSFHandyman To my amazement, not only had he shown how to make a mold for making LEGO candy, he also made LEGO gummies as well! I played around with loads of variations in recipes to see what texture and tastes I liked the best. And I've kept experimenting off and on for the last 4 years, using my kids and wife for feedback. They gobble them up no matter what variations I use, but I've finally settled on 1/2 cup of very cold water, 1/4 cup of corn syrup, 2 packets of unflavored gelatin, and 1 pack of Jell-O. I've found that the corn syrup seems to help smooth out the texture and the taste. If you try making this recipe, it's very important to start the gelatin in cold water. Stir it up, then let it sit for 5 minutes before you turn on the heat. Otherwise, you'll get gobby clumps of undissolved gelatin in your syrup that doesn't look very appetizing. I originally made my silicone mold with a 2 part mix from a special effects supply company. I used real LEGO bricks set on a LEGO base, and built a makeshift retaining wall with bricks and play-dough. I don't plan to make a tutorial on how to make the mold, but I want to do a video on how to make a silicone mold in general. It's amazing to see how much detail the silicone can transfer to the final gummy products. If you look closely at my candies you can even see the little “LEGO” text on top of the gummy LEGO studs. To make sour gummies, we often add citric acid. They are incredible! But if you don't have citric acid, try taking SFHandyman's suggestion and add vitamin C. The citric and ascorbic acids in the vitamins sour them the same way, which actually makes them taste just as great, and enriches them with vitamin C as well.
