Chemistry is Cool!!

And the videos at this link prove it. :hihi:

Hmm, magic, right there in front of your eyes, it is definately cool.

 

Levitation, demon voices - "I am your father Luke" :) And that's just the sulfur hexaflouride

 

You could embellish a few of these with some theatrics and be a legend at childrens parties :hihi:

 

But you know what they say in show business. "Don't work with thermite and children."

Who has a favorite, and why?

Very nice videos!

I really like the sulfur hexafluoride. I've been trying really hard to find some for quite a while now, because I've always wanted to experiment with it... but no such luck. Looks like fun stuff though!

I liked #8 the best because disintegrating gummy bears, or anything else, is always fun. :lightning

[Monomer]

Just saw the videos - they were great!!

 

The one that got the biggest reaction out of me was Sodium and Water in Chlorine Gas, but I also liked the Meissner Effect and Sodium Acetate Super Saturation. And Superabsorbent Polymer and Floating on Sulfur Hexafluoride... :eek_big:

 

Very cool!

I think we all agree that the Sulfur Hexafluoride one was absolutely cool amongst all cool things...great selection of videos by the way.

Let's do some chemistry with it. The average molecular weight of air is 29. SF6 comes in at 146.60 or 5.10 times as dense as air . (A molar volume is a molar volume, 22.4 liters at STP.) Can we do better? Sure! Make something volatile by perfluorination and symmetry (removal of dipole moment). IF7. bp = 4.77 C, colorless gas. MW = 259.89 or 8.96 times as dense as air. It's smelly, reactive, and toxic. Can we do better? Sure!

 

US Patent 3992424. Take your perhalogenated whatsis-X, microwave plasma with F3C-CF3, swap partners to get whatsis-CF3 and CF3X. I(CF3)7 is perfectly reasonable and most likely gaseous at room temp or slightly above. MW = 609.95 or 21.03 times as dense as air. A two-liter bottle of air contains 2.6 grams of air (piffle) or 54.5 grams of I(CF3)7 - and that's perceptably heavy. U(CF3)6 is "a very volatile solid," MW = 652.

My favorite chemical affect was performed by my freshman chemistry professor. It was called the beating heart experiment. A blob of mercury is placed in a dichromate solution with a little sulfuric acid. The mercury is touched with a nail. The mercury started to beat like a heart. It can do some morphing between shapes.

 

Here is video link that explains it. YouTube - Pulsating Electrochemical Reaction: Mercury Beating Heart http://www.youtube.com/watch?v=0hxt6hd-wV0

HydrogenBond,

 

Out of your almost 1800 posts here, this one has got to be your most coherent and cool. Thanks for the neat video. Perhaps I would enjoy your posts more if you used fewer words and more videos! :lol:

 

 

Take it easy, you conceptual cowboy.

You're exactly right, according to wiki it is used in magic shows, and is sometimes referred to as being "invisible water".

Yes, this. I thought I was sold when I got to the Meissner Effect, but the Sulfur Hexafluoride one was definitely the most visually impressive.

[Isomotopes]

I loved the Meissner Effect because i could just see it being able to implacate some sort of hover vehical

[koji8123]

#2 is my favorite because i want to see what thermite does in magma.. or something equally as hot or hotter.

[harmonSmith]

I have seen these videos before. very cool videos and ya chemistry is magic

Six pages of some more really sweet videos. Enjoy. :)
