Swift Posted August 18, 2006 Report Share Posted August 18, 2006 Ok. I was thinking drinking some pepsi today, and i thought 'I know! I'll make it ice cold!' So i put another sealed can in the freezer. 10 minutes ago (it had been in there all day!), i go to the freezer, I open it and i find this: Main part of freezer... Freezer door. So after that i had to boil and hack away the ice to clean it up before my parents saw it! [edit]: Here's a close-up of the can. Link to comment Share on other sites More sharing options...

ila Posted August 18, 2006 Report Share Posted August 18, 2006 Now that all the bloody pictures have shown up: Damn! That thing really did go nuts. When it happened to me when we stored pop in the garage the cans maybe cracked a little, but not explodey . Link to comment Share on other sites More sharing options...
DimensionWarped Posted August 18, 2006 Report Share Posted August 18, 2006 I've frozen pepsis before without having any problems at all... On the other hand, whenever I freeze drinks... its in a bottle and not a can. Link to comment Share on other sites More sharing options...
Guest Shadix Posted August 18, 2006 Report Share Posted August 18, 2006 I've definetely heard of this happening before, but I've never been victim to it and kinda dismissed it as an urban myth (guess not )... Of course I only result to freezing pepsis in emergency situations. I've forgotten about them a few times too... :\ Link to comment Share on other sites More sharing options...
Aerosol Posted August 18, 2006 Report Share Posted August 18, 2006 now take some mentos and put them in a bottle of coca-cola. Fun! Link to comment Share on other sites More sharing options...
Smidge204 Posted August 18, 2006 Report Share Posted August 18, 2006 My boss put a can of soda in the freezer part of the fridge in our office. It's one of those half-height ones, so the "freezer" is just a metal box in one big insulated cavity. Because of the size, he laid the can on its side. This was a friday. Over the weekend, the top of the can had burst off, and the can hit the door hard enough to open it. Quite a mess to discover on a Monday... Fun fact: When the soda actually freezes, it drives the carbonation out of solution. This, plus the slight expansion of the water, causes the pressure in the can to build up. The slightest defect in the can will cause a rupture. Plastic bottles fair better because the plastic stretches easier. =Smidge= Link to comment Share on other sites More sharing options...
DimensionWarped Posted August 18, 2006 Report Share Posted August 18, 2006 If I'm not mistaken, the bottles also contain less CO2 in general. It certainly feels that way while drinking it. Link to comment Share on other sites More sharing options...

hRook Posted August 18, 2006 Report Share Posted August 18, 2006 Fluids expand when frozen, as does the pressure, if I'm not mistaken. Link to comment Share on other sites More sharing options...
DimensionWarped Posted August 18, 2006 Report Share Posted August 18, 2006 Well kinda, Pressure * Volume = moles of gas * universal gas constant * temperature. Ideal gas law. liquids occupy a set volume and don't increase in pressure untill they change states. Gas (liquids and gasses are fluids) compresses as it gets cooler. When frozen, the crystaline structure forces the water to take up more volume than it would normally and there is no room to expand so there is a pressure increase causing it to explode a sealed container.

Asuma Posted August 19, 2006 Report Share Posted August 19, 2006 Wow. I froze water in a ballon and it didn't pop. I filled it up until it was ready to pop. When I open it up. It looked like an egg. So, I used a foam cup and put water in it along with my "ice sculpture" and froze. Cameout looking like a penis lol. Anyways, this samething happend to me, expect, it was with a sprite.

donnyku Posted August 19, 2006 Report Share Posted August 19, 2006 what's fun is keeping a can of soda in direct sunlight for hours, then suddenly thowing it.....BOOM! Link to comment Share on other sites More sharing options...
Swift Posted August 19, 2006 Author Report Share Posted August 19, 2006 Also, I remembered that metal contracts when it's cold, doesnt it. So aswell as everything else that people have said, the metal contracting may have had something to do with it too. And did i mention that the part that the ring pushes down was curved upwards? I'm glad i wasnt there when it happened... Link to comment Share on other sites More sharing options...

Smidge204 Posted August 19, 2006 Report Share Posted August 19, 2006 Fluids expand when frozen, as does the pressure, if I'm not mistaken. This is incorrect for two reasons. First, "fluids" include both liquids and gasses. Second, there are very few materials that decrease in density when transitioning from a liquid to a solid. Water is by far the most famous, but only materials that have a defined crystal structure which is lss dense than the liquid state will expand. This includes silicon, for example. =Smidge= Link to comment Share on other sites More sharing options...
Epon Posted August 19, 2006 Report Share Posted August 19, 2006 Pressure traditionally goes up when energy/heat/whatever is added. P * V = m * R * T Since R is a constant, when you adjust "T", the temperature of the system, it directly influences the equivilence on the other side. So if the volume and mass are static, then the only way for this system to stay in equilibrium is for the pressure to increase, thus why ____ explodes (read: I did not say combust) Link to comment Share on other sites More sharing options...
DimensionWarped Posted August 19, 2006 Report Share Posted August 19, 2006 m should be n actually. I don't know why persay they didn't just say "moles", but instead they opt for "number of moles". Link to comment Share on other sites More sharing options...
FuzzMaster Posted August 19, 2006 Report Share Posted August 19, 2006 I recall in science 8 being told "everything shrinks, if only a tiny bit, when cold". I asked why bottles of pop explode, and that's because water expands, though I was never told why it does. Link to comment Share on other sites More sharing options...
Serephim Posted August 19, 2006 Report Share Posted August 19, 2006 My mom does this crap EVERY time she buys a soda, and i have no clue why she wont catch on to it. But its never exploded THAT bad before. Link to comment Share on other sites More sharing options...
