InfiniteNow Posted April 14, 2008 Report Share Posted April 14, 2008 And the videos at this link prove it. :hihi: Top 10 Amazing Chemical Reactions - The List Universe Quote Link to comment Share on other sites More sharing options...
Ahmabeliever Posted April 14, 2008 Report Share Posted April 14, 2008 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.

Mercedes Benzene Posted April 15, 2008 Report Share Posted April 15, 2008 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!

freeztar Posted April 16, 2008 Report Share Posted April 16, 2008 Who has a favorite, and why? I liked #8 the best because disintegrating gummy bears, or anything else, is always fun. :lightning Quote Link to comment Share on other sites More sharing options...
Monomer Posted May 3, 2008 Report Share Posted May 3, 2008 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! Quote Link to comment Share on other sites More sharing options...
LJP07 Posted May 3, 2008 Report Share Posted May 3, 2008 I think we all agree that the Sulfur Hexafluoride one was absolutely cool amongst all cool things...great selection of videos by the way. Quote Link to comment Share on other sites More sharing options...
UncleAl Posted May 3, 2008 Report Share Posted May 3, 2008 I think we all agree that the Sulfur Hexafluoride one was absolutely cool amongst all cool things.... 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.

HydrogenBond Posted May 6, 2008 Report Share Posted May 6, 2008 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.

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. Quote Link to comment Share on other sites More sharing options...

"Don't work with thermite and children."You're exactly right, according to wiki it is used in magic shows, and is sometimes referred to as being "invisible water".Sulfur hexafluoride - Wikipedia, the free encyclopedia I think we all agree that the Sulfur Hexafluoride one was absolutely cool amongst all cool things...great selection of videos by the way. 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 Posted May 27, 2008 Report Share Posted May 27, 2008 I loved the Meissner Effect because i could just see it being able to implacate some sort of hover vehical Quote Link to comment Share on other sites More sharing options...
koji8123 Posted July 2, 2008 Report Share Posted July 2, 2008 #2 is my favorite because i want to see what thermite does in magma.. or something equally as hot or hotter. Quote Link to comment Share on other sites More sharing options...
harmonSmith Posted December 30, 2008 Report Share Posted December 30, 2008 I have seen these videos before. very cool videos and ya chemistry is magic Quote Link to comment Share on other sites More sharing options...
