Top 5 Deadliest Substances on Earth

a 150 lb adult would need to finely chew near at least 200 -5000 apple seeds or more to get a fatal dose of cyanide. https://www.medicalnewstoday.com/articles/318706.php. nausea, vomiting, and headaches would probably keep you from accidentally ingesting nearly enough to kill you. if you don't chew them they would not poison you. if you have ever tried chewing apple seeds you know they are disgustingly bitter.

"Causing vomiting and diarrhea which is often mistaken in emergency rooms as the flu" I just want to point out that calling that stuff "flu" is a misnomer as Influenza doesn't have any gastrointestinal symptoms.

The volume of this video is comparetively lower if you noticed

s ford - 2017-11-29
Figures such as "5/10000 the weight of a paperclip" are a little misleading. Great video otherwise, but normally, one would say "1/2000th the weight of a paperclip." If not for that, it'd be just as easy to say "50/100,000 the weight of a paperclip" which sounds much smaller than 1/2000. Doesn't it?
