AI Thread Summary
Sealing a box with a block of CO2 can create dangerous pressure, potentially leading to harmful outcomes. While it may not necessarily kill someone, it could cause serious injury or frighten individuals nearby. A past incident at a science fair involved dry ice in a pressure cooker, resulting in a significant explosion that startled everyone present. Demonstrations with liquid nitrogen have shown similar explosive effects when combined with warm water. Overall, experimenting with sealed CO2 or dry ice poses serious safety risks.

Ok let's see... what would happen if i completely sealed up a box with a block of CO2 in it (with room to evaporate).

My hypothesis is I create an incredibly dangerous pressurized box ready to kill someone. Am I right?

How much room?

Kill? Maybe. Maim? Little more likely. Scare the whey out of somebody? You betcha.

Some idiot pulled a similar stunt at a science fair at one of the local schools around ten years ago --- dry ice in Mom's pressure cooker. The table it was sitting under jumped a couple feet in the air --- the people in the room with it did likewise.
 
Basically a mini-fridge hehe.
 
I saw a demonstration once. Fellow put some liquid nitrogen in a plastic pop bottle ( 2 liter). Then he tossed it into a barrel full of room temperature water. Run away! Run away! Where's my umbrella?

Never tried it with dry ice, hmmm.

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
