it was 1967. our physics teacher took the class out to the parking lot. he wanted to show us the power of sodium so he threw a big chunk he had on the end of a butterknife into a bucket of water. well .... that blew everything in the bucket straight up into the air. i heard someone say ..... where is the knife? we all started running ......
Hello, we did that when i was at school. But it was in the classroom. She put a few small bits in and they fizzed about. We got her to put a bigger chunk in and boom. Water and fizzing sodium metal everywhere. Oh what fun When fire brigade turned up and evacuated the school.
Chemistry teachers all went crazy on the last day of the school year. Favorite experiment was to fill a tin with methane and light the tiny hole in the top. Nice flame, like a candle, which shrank and shrank, then flickered and seemed to go out. Then - BOOM! The lab shook, and the lid flew off and embedded itself in the ceiling tiles. Teachers were coming in from all over wondering what in heck we were doing. Excellent end to the year!
As a chemist, I'd say that's really more a uniform and professionalism concern than any real and significant exposure risk on this experiment. The water won't be alkaline enough to do anything significant to skin and is not likely to be more than warm to hot rather than scalding. Eye protection was correct. The water would get alkaline enough to really sting and perhaps even injure eyes, and the force of the reaction could also throw plastic and pebbles and unreacted sodium with the water, and those would all present substantial risk to an eye.
She used only half of the canister, she said she did that three other times, the canisters were to remove any possible Sodium to make it safe for other classes and to keep the tennis courts somewhat alright and clean
Nitrogen Trichloride, interesting.. I'll try to, but its on school grounds, so the teachers have to respect the safety of the school and the kids. So it may not be possible, but we'll try
@@PoorMansChemist No, no, it's fine, I did some editing to hide other kids faces as best as I could to avoid any issues with the parents, but my chemistry teacher said that she'll look into the Nitrogen Trichloride and see if it's within school regulations
@@Milesthecosmicfox Oh you're a student? Yeah that's not going to work doing that at school.. Nitrogen trichloride will explode if it is heated, subjected to shock, exposed to sunlight, or if it comes into contact with organics The compound can only be synthesized in glass. So in other words if it explodes it's going to spray you with glass shrapnel.
I think I was grouped with a class that wasn't considered mature enough to expose us to tools that would potentially up our pranking skillset. That was likely a good call on their part. 😏🧪⚛️

2:57 dude sounds like one of the kids from Haha You Clowns 😂
I remember having one of the greatest chem teachers in HS. Mr Jolly would do fun, interesting things to make learning fun and interesting.

Damn, sounds like you had a blast, but all jokes aside, hope y'all are okay.

I'm glad she put on goggles.
I was watching the first half going where is her PPE!?!?! lol
@@tattootempest i hope the kids had safety glasses on too
@@johnwhorfin5150 We did, we may be young, but we weren't dumb.
Not sure I fully trust a science teacher who says X "shouldn't be" Y without any kind of explanation.
Good safety third video.
She shouldn't have her ankles exposed when dealing with chemical reactions.

It was plenty enough ppe. Wouldn't be concerned.
had to show off the tattoo
Well, she knew what she was doing, and I can't control my teachers, plus she's done this for 10 years straight, so she's got this safety thing.
So what else was done that day? Please tell me your teacher didn't lug out two big canisters of water just for that.

@@Milesthecosmicfox Gotcha, seems reasonable. And you not taking a video of her cleaning the ground was a good call for content creation 😂
Do NCl3 next 😁😁

@@Milesthecosmicfox Okay if there's going to be kids around probably not a good one to do. My bad I misunderstood how you were doing these.

Nitrogen tri iodide might be a more acceptable option but I suspect both would be difficult regulatorialy speaking.

Probably a smart move, although it would've made a banger youtube short or tiktok, ngl
@@Milesthecosmicfox Those didn't exist. My chemistry class was in 1989. 😁All that happened was me accidentally breaking a beaker.
