Inhaling helium can make your voice sound high. But there is a gas that does the opposite and makes your voice sound lower - sulfur hexafluoride. It is potentially dangerous so don't try it at home.

In case anybody was wondering, sulfur hexafloride is not poisonous per se, but because it is so dense, it goes down, stays in your lungs, stops oxygen from getting in, so you suffocate, and... yeah. Not good.

So it isn't a poison, but it is a suffocant. (I'm not sure that is a word)

It’s also a greenhouse gas.

That's what most people would be worrying about as they suffocate from an excruciating buildup of heavy gas in their lungs, that they had just contributed 0.000000000000001% to everybody else's global pollution.

Simple way to get out of this is is to only breath a little at a time and hang upside down every now and then until you breath and speak normal. Lots of videos on YT about people breathing this stuff in, and other noble gases

AKA not having the gas pumped out of you from a hospital. You'd probably be dead by then

I'll bet you have never heard anyone say 'peruse' in your lifetime. It is usually in reading material where the meaning is obvious.

My teacher uses it quite often, but she believed it only meant to read thoroughly. I tried to explain that it could mean both, but she ignored what I was trying to say and heard me saying that the skim through definition was wrong.

i don't think that China having one time zone causes the sun to rise 3 hours later. That's just due to the size of the country.

If you use the official time zone, then it's true.

Inflammable used the prefix, "in-"

Normally it means in/out/not.

BUT...

In it, the prefix means, "to cause to"

Flammable means to set fire.

So, inflammable means to cause to set fire to...

...which is basically the same thing.

Thanks for coming to my Ted Talk.

If something is flammable it means it can be set fire to, such as a piece of wood. However, inflammable means that a substance is capable of bursting into flames without the need for any ignition.

Fwiw, the sun will rise earlier in the Eastern part of the country regardless of the number of timezones.

Yes, but in the US, the sun theoretically can both rise in California and Florida at 6:00 because of time zones. If we did it like China does it with only one time zone, the sun in Florida would rise at 9:00 instead of 6:00.
