I literally just bought one of those clicker heater things @ a thrift store, bigger, meant for neck & shoulders, for $3 (say, 30-45 min ago). I believe these manufactured ones are silver acetate. I know they work by making a superdaturateed soludion that precipitate out of solilution when disturbed by the clicker, or your spring snapping. The bonds breaking release energy as heat. It'd be cool to be able to make my own, though. Kudos for your video!!
welding.. you should DIY welding electrodes for stick, that can be used with a welding machine made from microwave- you can get flux core wire that doesnt require shielding gas as well.. maybe if you make some device that can work for a TIG welder that would be quite something. maybe slowly pumping air through charcoal, nitrogen CO2 and CO comes out. but for TIG welding we usually use like 10 bars of gas interesting with spring to crystallize, never seen that before as chemist
In United States concentrations of 70% vinegar is considered a hazardous chemical, typically even cleaning vinegar is only at 6% so it is not readily cheap in store which typically only has a 3-5% diluted solution as per legal law for food stores.
The spring gives a shock wave and because of this shock wave the composition begins to crystallize and heat up. After recharging by boiling, everything is ready for new use. 🤖
Well, it looks pretty cool but , 🤔there wasent explanation to what we were really seeing. 👀First you start off talking about a heater with no explanation for what it is and how and why it works, then you start telling us of other cool ideas you had, and did, but then you go back to the original story without explanation of anything like you saying, just guess whats happening and why, I'm not going to explain the spring or how things function or why, hope you liked the video. WHATS UP WITH THIS STORY?🤔
No it's not. You can buy 25% in german supermarkets with no problem. And looking through my usual online chemical providers I immediately found a German source for 100% acetic acid, where you don't even have to be 18, a Dutch one; same conditions. And a Polish one; same thing. At least the first two are absolutely proper, no funny business. The Polish one is kinda scetchy when it comes to transport safety. But none of them sell prohibited chemicals to private citizens.
One consistent Haye for all of your videos is how ypu don't stay on topic of what video is about. You always add clips of completely different things you have made. Stop doing that.
I've always wanted to make a hand warmer like that, didn't know it was as easy as just heating up sodium acetate, I think you can even buy sodium acetate as is here in sweden
