ComradePyro posted:I think it's fine to acknowledge the danger, sure, but the "Do not do it!" tone is counterproductive ala drug PSAs overstating the dangers of jazz cigarettes. People do it all the time without hurting themselves even though it's dangerous, so it's clearly not that dangerous. We talking helium breathing or table saws? I mean, definitely don't combine the two e: my first snipe ever, huzzah dobbymoodge fucked around with this message at 14:51 on Apr 5, 2024 |

Whole house shook at 10:25. 4.7 earthquake under central New Jersey. I thought my foundation failed, or my one last old tree fell over.

I actually did this for a science presentation in highschool. Can't imagine the poo poo I'd get into today doing that

ethanol posted:how many normal sized balloons of hydrogen do you think you could string together and pop before it becomes dangerously concussive One YouTube channel or another (I can't remember the name, the one where the presenter is an older man from Maine) did a video on this topic, and the conclusion was hydrogen burns too slowly. You need a premix of hydrogen and oxygen in the right ratio to get a really good concussive blast.

You need a premix of hydrogen and oxygen in the right ratio to get a really good concussive blast. yeah that's what I was leading at.. and you probably get a bigger bang with a single balloon without the sort of chain reaction going on there, but even then.. needs to be premixed to really do some damage.. but I assume there is some size where it's still going to make a big enough bang? or will it just hindenberg / be more flames unless it's premixed. is there a point where you have so much hydrogen / not enough oxygen it's less concussive and more of a slower flame front like that I guess is what I'm asking.. or will they all pop with the same brief snap you see in a science class with a single baloon but in quick succession. I want a demo vid on it thanks ethanol fucked around with this message at 17:28 on Apr 5, 2024 |

Safety Dance posted:Discount hydrogen balloons and a firework birthday cake! Those balloons with stuff inside of them often have cornstarch inside them to keep the stuff sticking to the balloon. If it was hydrogen, the flame would be nearly invisible. St_Ides posted:Because the US government sold off the strategic helium reserve and the price of helium skyrocketed. The price of getting a t-tank of helium went from 200 bucks to 650 bucks in like a year. We got out of doing helium because of it, and sometimes you just can't get it at any price for party stuff since medical has first call, and manufacturing has 2nd call.

LimaBiker posted:I don't think the balloons are filled with hydrogen. Rather, natural gas, which is also lighter than air, and a LOT cheaper. The color of burning hydrogen is less yellow-orange, more red, and less opaque. It also burns a bit faster in my small scale experience. I'm not sure natural gas is lighter than air?

mobby_6kl posted:https://i.imgur.com/vlLXjMH.mp4 I think the idea is you leave it on, and someone will take it off of you during the course of your surgery. IMHO you shouldn't rely on this tech alone, but rather as part of a comprehensive approach to dong safety.

Semi related to tablesaw chat, I'm hopefully about to become a homeowner for the first time ever and I'll need to Do Some DIY at some stage which will require some power tools. Sander, circular saw, drills/impacts, and other things you would use round the home when doing renovations. Is there like, an Idiots Guide to using stuff like this safely enough that you don't risk losing fingat for people who never took shop class?

The russian helium import was the response to the national helium reserve being effectively destroyed. They were having to ship conexs full of t-tanks of helium cause there wasn't enough shipping to handle big lots of it across the ocean.
