I advised someone a while back on another forum not to try doing what he'd seen in that video. It seems alot of people have seen it and decided that they knew everything they had to know about casting metal, and hadn't looked any further.

I'm having a hard time wording how the video makes me feel, so bear with me. I think the guy is a ****. He's making little easily digested 'science experiment' style videos aimed at the 'lifehack' crowd, which I have nothing against, except he's encouraging people (and most likely kids) to try do something fairly dangerous at home without any understanding of the hazards involved. He's not given any warnings about potential dangers, and even suggested that putting cans with soda left in them into the molten metal is totally safe.

I hope the guy's just an idiot, but with his weaselly little hidden disclaimer in the video description it feels like he intentionally neglected to mention it in the video itself to make it more likely to get posted about. It wouldn't be half as appealing (to his target audience) if the guy admitted 'this is really dangerous and you probably should read into it more before trying it out for yourselves'.

Anyways sorry to be grumpy about it but this stuff just really frightens me. It's the kind of thing I might've tried out when I was 13 and didn't know any better.

The really glaring health issue to me is the burning of synthetic can coatings and particularly the non-stick coating on the muffin tin.  Many flourine based modern coatings like PTFE when degraded by excessive heat (well beyond the rated cooking temperature use in cookware) are extremely hazardous to breathe.

The dsclaimer "Use common sense," is ludicrous. Not everyone is aware the seriousness of the hazards involved other than the obvious high temperatures.

Aluminum for melting should be clean, and plain uncoated steel molds should be used for ingot making, in case someone here doesn't realize it.....understandably.

Thanks for sharing that quite a good little crucible set up NOT.

Its grossly unstable being a bucket shape wider at the top easy to tip pouring hot molten metal and charcoal onto a person or surface.
The blower tube and hair drier set up like he had a gust of wind and instant fire or burnt person.
Let alone the tube inserted my also melt with the heat and the heat travel along the tube to the plastic one hot melt plastic.
Kitchen tongs please I've picked up a set of tong resting near and edge of a BBQ and dropped them just as quick due to radiant heat.

As the fellows above have said "DangerMan"

Other things spotted was very little PPG personal protection gear, sneakers ? nylon sox? nylon clothing? :jaw: :jaw: all these will and can ignite standing near an open fire or BBQ.
