Super Cooled Liquid Gold

I show what happens as a drop of gold cools.

ayyy lmao. I subbed at 2500 subs when you were insanely thankful for 5000 views in a day. You're growing alarmingly fast Cody, I love this channel and thankyou for all the content.

[odysseus]

I love your videos Cody, youve inspried me to major in chemistry and from there I took it to chemical engineering which is an incredibly hard major, but your videos inspired me to gett towhere im at today, just wanted to thank you for that,

[slinkyweasel]

I showed your channel to my science teacher. I have to thank you and my mom (also a science teacher) for getting me into advanced of course my teachers in the past too but I spend like 24/7 on yt and with my mom...

A fascinating demonstration, thanks Cody. It's 3:30 in the afternoon here.

Cody I'm glad to see that you're uploading daily the only reason that you weren't my favorite YouTuber was because you uploaded weekly but now that you're uploading daily you're by far my favourite. Keep up the good work!

[debiesu]

It looked super neat the first time, it's something I'll watch again a few times now that you've explained it. Thanks much!

[ottawaurban]

this is so cool. I observed this for the first time today while doing some silver fuming with my glass work. Instantly reminded me of this video. thanks for helping me understand whats happening cody!

[EngineerNick]

Thank you i couldn't find this when googling it after the last video.
You continue to be one of my favourite youtubers :)

Thx a lot for this video, I was looking for an explanation as to why gold glows right before it solidifies but I hadn't thought of supercooling so I couldn't find anything online. Glad to hear the explanation!

[CroissantCreates]

I am really liking your newer style to videos, it's very entertaining and always fun to watch. Keep it up Cody

[wmlemming]

Cody, you're amazing. Your love of science is very energizing. Thank you.

[mpcabete]

Cody has the best channel on YouTube, this must be a reflection of he as a person!!

[AwesomeBrony]

omg! yes! i actually tried looking for videos on a gold bead cooling right after i saw your video but failed... glad you made another specifically for that. thank you. :)

[texasdeeslinglead]

dude this may be one of several of your videos that is bad ass

[HenriBorov]

man this channel blew up so quickly, good job cody

[ryanhiggins]

I think you should do some episodes with "SmarterEveryDay", you guys are my two science related channels that I truly enjoy!

[BodilyFunction]

Hey Cody thank you for introducing me into the world of bees I'm getting a scholarship giving me a box of bees and all the equipment to do it I'm still watching your year of bee keeping videos and I'm learning a lot

[OpiumBlxntz]

Cody you are my No 1. favorite youtuber. I personally LOVE science and you have taught me so much. im only 12, and ive learned far more than a 12 yr old should lean and my parents think im amazing becuase i know all of these facts i know, and its mainly becuase of you. im gonna tell all of my friends about you and hope that the word spreads about how great of a youtuber you are.

Really cool phenomenon, quite impressive that the change from liquid to solid releases that kind of energy, I guess gold being a really good conductor helps ?

There is an instrument used to measure water in milk. A milk cryoscope.
It has a semiconductor based peltier cooler cooling a Glycol bath.
Milk is placed in a small test tube and lowered into the bath. A temperature sensor is lowered into the sample and also a rigid wire.
A pulse of movement is induced in the rigid wire (something hits it) The sample then releases a tiny amount of heat.
The amount of water in the milk can be determined by the heat released.
