Allassonic/Hot Chocolate Effect

newtboy says...

Works with most hot liquids with powders, I think I first noticed it in a mug of instant hot cider......

https://en.m.wikipedia.org/wiki/Hot_chocolate_effect

The hot chocolate effect, also known as the allassonic effect, is a phenomenon of wave mechanics first documented in 1982 by Frank Crawford, where the pitch heard from tapping a cup of hot liquid rises after the addition of a soluble powder. It was first observed in the making of hot chocolate or instant coffee, but also occurs in other situations such as adding salt to supersaturated hot water or cold beer. Recent research has found many more substances which create the effect, even in initially non-supersaturated liquids.
It can be observed by pouring hot milk into a mug, stirring in chocolate powder, and tapping the bottom of the mug with a spoon while the milk is still in motion. The pitch of the taps will increase progressively with no relation to the speed or force of tapping. Subsequent stirring of the same solution (without adding more chocolate powder) will gradually decrease the pitch again, followed by another increase. This process can be repeated a number of times, until equilibrium has been reached. Upon initial stirring, entrained gas bubbles reduce the speed of sound in the liquid, lowering the frequency. As the bubbles clear, sound travels faster in the liquid and the frequency increases

I'd much rather Starbucks because when you ask for a latte, they make you a latte. They don't put a cup under a machine and it dispenses powdered milk and a tiny drip of instant coffee.

I miss the coffee in Melbourne. The best I've had here is from a popular cafe down the road from work called Olimpico. They're latte's are small, but damn good. If you're in the Mile End area of Montreal, check it out.

Ya, microwave distilled water for 10mintues then add something to it like instant coffee and BOOOM!!!!!

[edit] Wont work with regular water. The impurities in tap water will cause it to boil in the microwave. Though some bottled water will do it so be careful when microwaving your morning cup of coffee heh.

Neat. I've seen this done with water, but not with beer.
You can also do something similar by pushing the temp of a liquid past its boiling point, except instead of freezing it tends to explode.

No i prefer to reply to comments where they are posted. Sorry if that breaks your own code of practise, but I frankly don't give a crap. You are a moron. get over it.

My only argument was that if you can't grate cheese, you should just give up on life. After two years on the sift and you still don't know how to reply to a comment: you're probably the perfect candidate for pre-grated cheese.

Oh, I'm sorry, I clicked a button that posts a quoted reply to a comment posted ON my profile page. How exactly does this help your argument? You're still wrong <IMG class=smiley src="http://static1.videosift.com/cdm/emoticon/tongue.gif">

Are you fucking serious?

sliced bread, tossed salad, instant coffee/custard, bottled water...dude you didn't have a salient point to begin with. stop trying to defend it.
>> ^Ryjkyj:
If grating cheese is as hard for you as owning a transportation company, farming, milking and fermenting then you've got serious problems. Pre-grated cheese costs around twice as much and tastes so much worse. To each his own, but I hardly think grating cheese qualifies as an inconvenience.
That's like saying wiping your ass is an inconvenience.

Oh please. Convenience is such a crime.
Tell you what next time you open the fridge, don't take anything out of it that you haven't grown, processed, packaged and transported yourself. In fact why do you even have a fridge. You never built it yourself and you certainly aren't powering it with electricity you are generating yourself.
Did you milk the cow? Did you provide the cow with green pastures to frolick in? Did you? No. So shut up then.
>> ^Ryjkyj:
People who by pre-grated cheese should just give up. Give away all your worldly possessions, get a job at Walmart and start eating all of your food out of a dumpster. You obviously don't care enough about life to do anything besides eat at Wendy's and watch American Idol.
If you read that statement and think, "gee, that's a little harsh, grating cheese is annoying" then try getting yourself a box-shaped cheese grater. The flat ones are for trimming knuckles only. If you still think it's annoying, then follow the above instructions. Or better yet, open a vein.

Now see, when you hit the "quote" button, it's just going to post to your own page. If you want to respond directly to me, then go to my last comment and hit "profile reply" down on the bottom right side of the box. That way, your response to me will show up on my page instead of your own.

If you need any help learning how to grate cheese, you know where to find me. (but you'll still have to hit "profile reply")
