How to Make an Edible Apple Swan! (03:29)

The King of Random · 4 years ago
How to make a decorative, and completely edible, apple swan! I made a few modifications to the original idea, to get the effect you see here.

Music By: ("Little Voices" -- Instrumental). http://bit.ly/ScottBrendoiTunes Project Inspired By: A friend in England in 2001 showed me the idea originally. I also found http://youtu.be/FNXmuakUi4M to help refresh my memory, and then made a few of my own changes to make the swan look better and more attractive. I got the inspiration for using seeds as eyes in this video: http://youtu.be/jg6sWO3z0BQ Project History & More Info: I remembered someone showing me how to make an apple into a swan while I was in England in 2001. I can't remember who it was though, and I just remember that it was a nice try, and although the wings looked cool, and head and neck were terrible. I really liked the idea though, so I spent an entire day cutting up apples in different ways to see if I could make it better. I also saw a video online where someone used apple seeds to make eyes (http://youtu.be/jg6sWO3z0BQ) which was really awesome, so I tried to incorporate that in. I ended up with this method for making the apple swan, which I think really looks incredible, and we ended up putting them on display for some dinner guests we had that night.

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

The King of Random · 5 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.

A little Borax detergent booster, yellow and green food coloring, and a 5 oz bottle of some clear non-toxic school glue. Borax can be found as a detergent booster under the name "20 mule team Borax". It's a natural mineral with a chemical formula Na2B4O7 • 10H2O. The IUPAC name for borax is sodium tetraborate decahydrate. Borax also is known as sodium borate, sodium tetraborate or disodium tetraborate. If you don't have access to Borax, I've heard that liquid starch can be used instead. I haven't tried it, but let me know if you do, and how well it works? Just mix 1/2 cup liquid starch (eg. Sta-Flo) with an 8oz bottle of glue (should be the whole bottle).

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!

The Metal Melter (05:15)

Use of this video content is at your own risk. Music By: Music by Jason Shaw (RP-PilotsOfStone) http://www.audionautix.com Project Inspired By: codemsan Project History & More Info: By modifying the secondary coil on a MOT, the transformer is converted from a high voltage/low current device into a low voltage/high current metal melter. The first MOT in the video produces just over 500 amps, and the second one is capable of nearly 800 amps. Any metal that can conduct such low voltage electricity acts as a resistor between the electrode wires, and heats up due to the extreme electrical friction. I plan to make a new project turning this into a more proper and useful spot welder, although I can find very little use for a spot welder at the moment.
