  • Hi there, everyone.

  • This is some extra footage from an nitrogen tri iodide video again showing as we often dough that things don't always go according to plan in the chemistry lab.

  • Now, in the original video, you probably saw this.

  • We have, ah, Lego professor touching some dried out nitrogen.

  • Tri iodide.

  • It's a contact explosive.

  • So the result is obvious.

  • Oh, very nice.

  • Filmed very carefully now.

  • Often, we decided to film these experiments a second time, mainly so I could get better footage because I don't do a very good job the first time.

  • So here we are in the lab.

  • We're going to do it a second time.

  • We've got some wet nitrogen tri iodide on the hot plate, but it's getting near the end of the day.

  • We have to go home.

  • And when we first give it a try, as you can say, uh, no reaction.

  • The chemicals are still too wet.

  • They haven't dried out.

  • Now we've got them on a hot plate to help them dry, and you can see here we're trying to increase the temperature.

  • I think it was originally it's something like 50 degrees Celsius.

  • We go for 100 then decide.

  • No, that's too much.

  • Go back down to 75 because we don't want the heat itself to cause the reaction to happen.

  • Now, here we are, just waiting around for things to dry out.

  • And by, I think, more luck than anything.

  • I have got the high speed camera still running, ready to trigger on.

  • All the lights are still on.

  • And that's a good thing, because mid conversation suddenly we get this.

  • Oh, that's all right.

  • And I guess just reflexively.

  • When the reaction went off, I did press the trigger and captured the slow motion.

  • Here it is nothing setting it off except just the hate.

  • But if we look at that again, here's where we see a small problem.

  • We have some still wet nitrogen tri iodide off to the side here, being blown to the side of the fume hood.

  • That means we have small specks of wet night.

  • She didn't try higher, died in Neil's Fume Hood.

  • If you've watched every two years before, you know this is not the first time we've made a mess of the fume hood.

  • But the problem here is it's still wet, and when it draws, it's ready to go again.

  • So Neil got his little Lego man and started setting off the bits of nitrogen trial.

  • I died As they drive.

  • It'll snap, crackle and pop slight rice bubbles.

  • We also noticed a few little specks on the floor around the fume hood.

  • They were mainly being set off by my shoes.

  • And, of course, the equipment that's in the fume hood may have had small specks on it as well said you had to get all of that out and give it a good seeing T.

  • You go.

  • No.

  • Everything goes to plan in the chemistry lab, but it's always good that you see that as well.

Hi there, everyone.
