Liquid helium is seventy degrees colder than liquid nitrogen.Not if you give them liquid nitrogen--that'll freeze 'em.

she said his reaction was he saw her and jumped in shock
In the film The Entity, the scientists trap the spectre by freezing it, but this bit was made up, it never happened in real life. Do people think it's real now?
Well, then THAT would freeze 'em too!Liquid helium is seventy degrees colder than liquid nitrogen.
Helium gas is dangerous to inhale. I saw the high-pitched voice trick demonstrated and then tried it with kids and balloons.Well, then THAT would freeze 'em too!
If I'd paused a moment, I would have realized that it's helium gas, not frozen helium, that makes a voice become high pitched and squeaky.
Not to mention that it's ill advised to breathe anything that's frozen.
I have tried it just once, to witness the pitch change myself. However, I don't recommend people trying it lots of times in a row, especially if they have a low level of oxygen in the blood. After breathing helium in, it's best to expel it from the lungs ASAP, otherwise it can cause fainting.Helium gas is dangerous to inhale.

Could have killed someone.
You’re stopping the exchange of gases in the lungs so this will reduce oxygen content if done over a prolonged period. Helium being lighter than air is relatively easy to get out of your lungs. Some of the other noble gases have the effect of making your voice go deeper and because they are heavier than air they are harder to get rid of from your lungs, a friend of mine was hospitalised whilst attempting this for a TV show.I have tried it just once, to witness the pitch change myself.

I think that's simulacra!
Maybe a ghost would look shocked as the last thing it saw was the person or thing that killed them.
Maybe that's what all those moaning ghosts in castles are really doing: keeling over and saying "ARGH" as they did when run through with a sword. :fence:Wouldn't that mean most ghosts would be seen keeling over or silently going "ARGH"?
