Is there a physicist or possibly chemist in the house.

If I take a block of dry ice and place it in a box exactly the same size as the block, then put on a very firmly fixed lid, what would happen?

 

[Raheem]

You'd get your answer.

 

[Shippou-Sensei]

Presumably the pressure would slowly ruse as it goes from solid to gass.

Perhaps at some point the pressure would be enough that it liquefied?

 

[Shippou-Sensei]

How insulated is the box?

Why do you want to do that?

 

[Magnus McGinty]

Is the chemist for when you burn yourself?

(Don’t be pedantic and say pharmacist ffs)

This is your Sunday challenge Sasaferrato

 

[farmerbarleymow]

How insulated is the box?

Or how well sealed the box is. The gas would escape unless its completely trapped, as it sublimates.

And FFS Sas - don't do your experiment indoors.

I am fairly sure sass was trained as a pharmacist, so I don't think he's posting about that kind of chemist, more the type that engage in chemical research/experiments

I'll await dessiato's recommendations on that.

I reckon he's up to no good.

Fess up Sasaferrato - what nefarious plans are you hatching.

Unless it's a very strong 'box' (see fbm's video above) it will just turn into a gas which could make the box distort/break.

Don't do as some mates did and stick some in the bog (in a club) hoping to fill the gents with fog. When nothing happened after a while they went back and flushed the loo. The resulting thermal shock caused the pan to break.

At ambient temperature with a sealed container? Expand, deform. Possibly rupture/explode.

Midges. The absolute curse of Scotland for much of the year.

What I was hoping was that the dry ice, being confined, would remain as a block, thereby allowing you to vent the box, and release the CO2 at a steady rate.

CO2 is what attracts the midges, the CO2 in your exhaled breath.

I was toying with the idea that releasing CO2 at a greater rate than breath CO2 might lure the little bastards away from people.

When I were a lad on Harris, the ice cream was delivered in insulated boxes and packed round with dry ice, this was still solid when it arrived. The cafe owner used to decant it onto the pavement, and we played football with it.

To answer the question..

"Never store dry ice in an airtight container. As the dry ice melts from a solid directly into a gas, the gas will build up in the container until it bursts. Sharp pieces of container will go flying all over the place."

But..

You could suck it and see??

In view of the link you posted, I'll leave that honour to you.

Couldn't you carry a CO2 cylinder around with you to do the job. Or just stay at home with the windows shut?

Do not suck dry ice! Do not put it in your mouth! The damage done could quite literally kill you, at best you'll get very bad burns.

I would definitely not suck it.

Speaking from experience?

Use a CO2 fire extinguisher to freeze the little gits.

I was a chemist in my younger days.

You could try a bucket of warm water with bicarbonate of soda dissolved then drop in drops of vinegar from the bottle.

 

[FridgeMagnet]

I remember going to a party where somebody (from the research part of the company) had just put some dry ice in a bucket and also some beers. It just sat there boiling away - didn't last very long but longer than I would have thought. Yes it was in the garden not indoors.

Don't bother with the water just bicarbonate and vinegar.

I didn't mean that literally.
More figuratively.

Nobody would suck dry ice...
