Cadbury Creme Eggs, Liquid Nitrogen, MRI Scans, and Extra Dimensions

The science education video series Sixty Symbols (previously) explores the Cadbury Creme Egg.

Mechanical force tests.
Eggs used to explain MRI signals.
Magic tricks with coupled pendulums.
Eggs used to explain six-dimensional particle physics.
And my favorite, chemical proof that the good stuff is in the middle.

Does the particle physicist start playing "In The Air Tonight" at some point?

Don't forget this link of Cadbury's scam involving the eggs!

Mum told them not to play with their food.

That was f'ing awesome. All of them. Great, great stuff.

The chemists seemed to behaving the most fun.

Exactly how is destroying delicious things ok to do now?

Mmm, I just had a Cadbury Creme Egg and then loaded Metafilter and here this was. I will add, having watched all the videos, that the warning on the particle physics one is most accurate!

Does this SCIENCE at any point confirm my suspicions that Cadbury Creme Eggs are made of crack cocaine?

I wish that that highly convincing "sugar is a poison" article (ah, here it is) had been posted after Easter instead of before, because maintaining my nascent low-sugar diet over the next few days is going to severely deplete my reserves of willpower. If there was a Haigh's shop in this city I wouldn't have a hope in hell.

A Thousand Baited Hooks

You know, the creme eggs have been in the shops for ages, I know there are public holidays starting from tomorrow, and it is only now, reading your post that it occurs to me that chocolate had better be forthcoming for the missus on Sunday or I am in the deepest poo. Thank God for you!

You can say 'fuck,' dude. We've all had our dirty words shots.

Whoa, the coupled pendula were awesome. I've never seen that particular result before (where each stops in turn). Also, Professor Bowley (I guess his name is) is really great. He looks like such a stuffed shirt but he does such a great job of explaining things and he's so...normal.

Fuck!

I always thought Neil was like a unionized "experiment setter-upper" or something, but if that's his lab....is he an experimental guy and all the others are theoretical or what?

Some other fun with coupled pendula: I like to anchor the pivot to a solid crossbar directly overhead, then you can slide the string that couples the two together up and down to vary the amount coupling. Then you can also have each pendulum have a different length (and therefore frequency): slide the coupling string to the bottom to and you can see that they both swing together with an average frequency. In the intermediate range, you see the effect shown in the video where the frequency is unchanged but the amplitude varies in time. A great way to explain why multidimensional NMR experiments like COSY and EPR experiments like ESEEM don't work if the coupling is too strong.

These are pretty cool!

Without knowing, I suspect that Neil is a Lab Tech whose responsibility it is to maintain the labs. The professors get to play with demos and then the lab tech has to come in and clean up after them. I seriously doubt one professor would be expected to be responsible for cleaning up a mess that another professor made while doing a demo (though anything's possible).

And 445supermag, that's an awesome demo idea! I may incorporate it into my class the next time I talk about 2D NMR.

Only 2 of those videos destroyed the eggs. I mean, the coupled pendula guy tells us to use hygenic needles if you want to eat the eggs.. so I assume he did.

and the MRI, well it might have messed with spin of some of their protons, but whatever. Still edible.

Particle theory doesn't seem to destroy eggs either.

Here's some particle theory from 60 symbols! Cool post.

I wish someone made a dairy-free, dark chocolate version of these eggs.

Why are they so beloved? They were first to go when I reached adulthood and my "just because something is made if sugar doesn't mean it's delicious" phase.

Why are they so beloved?

I can think of three reasons:

1. There really isn't anything else like them, at least not where I live.

2. They resemble an actual egg reasonably closely.

3. They're seasonal. The nine months that you spend without them adds to their specialness when they're finally available and is part of the reason for my love of persimmons and Darrell Lea nougat eggs (and they all come at the same time! What a great time of year)

Because destroying them is the only way I know to get them into my belly!

RE: why they're so beloved, I think part of it is just cultural - what folks associate with their youth. I recall when I first went to live overseas and started learning what it was like to live without all the things I'd become used to having here in the US. Oreo cookies used to be one of my regular grocery purchases in the States, but I couldn't find them in North Africa.

Finally a friend mailed me some Oreos from the US and I shared them with some of my local friends. Another expat, from New Zealand, I think, took a bite, scrunched her face disapprovingly, and said with some asperity "They seem to be rather bland."

I laughed off the comment at the time, but later realized she'd been right. Oreos, upon reflection, aren't very tasty cookies, at all. The "chocolate" wafer tastes nothing like chocolate and the "creme" filling tastes nothing like cream. I realized that it was just what I was used to, since childhood.

Since that realization, I virtually never buy Oreos anymore, instead opting for a dessert that actually has a taste that commends it. (A similar experience led to leaving behind Hershey's chocolate bars in favor of Cadbury and Lindt).
