Sodium and Iodine

Sodium metal and elemental iodine are mixed, producing sodium iodide, the salt used to iodize table salt. This reaction is quite vigorous and flaming sodium is shot out of the pyrex container twice, producing a large cloud of vaporized and re-solidified sodium iodide crystals. The reaction was hot enough to crack the pyrex.

For ur next video u should use Trinitrotoluene and light it on fire!!!!

[ExplosiveScience]

@TheH0U53 Haha, I actually have considered trying more powerful reactions such as the one you stated, but I won't because they are illegal. Modern American society doesn't understand passion for chemistry, but immediately assumes bad or violent motives. If I were to synthesize any powerful compounds, it would be felony. I try emphasize that science is educational and nonviolent, but I also try to keep it fun. Some people still don't understand, I have had a thermite video removed.

You should have done this in a closed container, at least it would contain all that I2 vapor or maybe have a tube that leads to some cold water. Nice video, thumbs up.

[ExplosiveScience]

@vmelkon Thanks for watching the video, commenting, and the advice. I actually considered using a closed container, but due to my lack of lab equipment, I was unsure of how to safely contain the I2 vapor without causing a pressure increase. As a result, this is a combination of 7 reactions, I simply assumed the sodium-iodine reaction would be most dominant because it is the most spontaneous and is favored by the concentration of reactants.

oooooooooooo weeeeeee......look out for that I2 vapor.....that s**t will stain the hell outta your clothes!!!!

[ExplosiveScience]

@LV07TSK Haha, that was the best part. When doing another experiment with iodine, I spilled some on a nice cotton T-shirt and was pretty bummed it was ruined. It formed a large brown stain which spread over the shirt, and 20 minutes later was totally gone. When you spill iodine on your skin or clothes, it rapidly sublimes away. I encourage you to try it, it's pretty cool (It doesn't work with iodine compounds, only elemental). Thanks for watching.

is that CRACK?

[LOLiver456]

COLLIN. my honors chemistry class is obsessed with you and your videos. keep up the good work! <3

[EthanFoley]

I have that same bowl.

@Agentoxedo07 Sorry I'm so late, but Google it if you dont know what its is.

[ampikine]

Where did you get the sodium? 

[iNFamousAAC]

@ExplosiveScience You should do the chemical chameloen reation :)

[739199]

@ExplosiveScience I agree. My school had a "science" project but after me and my friends got everything ready (we were basicly copper plating coins with Copper sulfate) but at the last minute our teacher decided it was dangerous. The other group was showing the properties of smoke from burning matches.

@ExplosiveScience I've got a funny picture I could send you of my hand after a flask of iodine volcanoed it's way out. It looked like I'd had it in the toaster for half an hour.

But if you get any more iodine mess, which you undoubtedly will if you handle it, because it IS filthy, remember that you can wash it off with bisulphite and thiosulphate. Bisulphite is sold at brewing shops to sterilise the demi-johns; sometimes as tablets. It works almost instantly and completely.

"WHY THE HELL you was using shorts??"

Wearing trousers wouldn't help much. Standing further back & not poking it would be a better safety measure.

"I hate that people have been brainwashed to think chemistry is only for evil."

The vast majority of people into home 'chemistry' seem to be 'pyros', who don't really know what they're doing. So there is some sense in the government being bothered.

"it takes pressure and heat, like a blasting cap"

Point demonstrated, wants TNT, wants it 'on fire'
