Not really, it's not fully wrapped in duct tape and the use of duct tape is what makes things like sparkler bombs dangerous instead of just a bunch of sparklers.
As for the rapid heating and cooling, exploding might be a bit much but there's a reason that you're not supposed to take certain metals from extreme heat to extreme cold.
Sorry that we're not all biology majors but even kids in elementary school know that you get oxygen into your lungs through your mouth and nose.
If you meant from your lungs into your bloodstream then I don't know the specifics of that one but it's tiny tiny amounts that is in a self contained system.
I did this, but I wanted to be edgy and used a knife instead of my fingers. I'm now in a ambulance, but did I do it right?
yep, it makes it weaker and easier to break for a moment but, it's not uncommon to put an extremely hot piece of metal (red hot) into cold water to accelerate the cooling and to be able to work it faster so...
Not just for smithing (other process have the metal go really hot, like strong and quick deformations) but yeah, better made by professional. anyway, most of the spoons and knife are stainless steel, so unless it's really shitty quality, it wouldn't be a big deal (don't try this with aluminium).
I think the shit comes from the duct tape 'cause heating then cooling stainless steel is not a big deal
More than likely whatever it was will just crack and become useless but the chance of it catastrophically failing is still possible.
Isn't silverware like the hot dogs of metal? What I thought anyway, could be totally wrong.
The duct tape could apply pressure/direct the force of it in a small focused area which is dangerous but I just don't see that happening with one spoon/knife.
It depends on the quality of silverware, mostly the good ones are stainless steel (mostly for hygienic reason) but you're right there's some shitty one. if the metal looks really thin and shiny, I wouldn't recommend to try even if it won't cause an explosion of some shit obviously
