Wouldn’t it need some sort of clamping mechanism to force the air out as it freezes?
AFAIK that’s the only way to get ice that clear.
I am sure it is nearly impossible to get the bullets that crystal clear. Anyway I want to buy one, and ship it to my brother in Iraq.
If you boil the water before you make ice it will be clear.
Or used distilled – the smaller shape of the bullet should make it easier to make clear ice.
There’s an idea whose time may, or may not, have come, depending on the phase of the moon, whether the stock market’s major indices are going to downtick in the last five minutes of trading, and the exact mass of the Higgs Boson.
Brings a whole new level to the Bloody Mary.
I’m curious how you’re suppose to fill both sides of the mold, then put the halves together without all the water pouring out, being as how liquid water reacts to gravity and all?
Reading the instructions on the site “fill one part with water until it reaches the top then place the next half on-top, press down then set in the freezer to create some cool and very realistic looking AK bullets!” I don’t know what physics are involved in that, but I’d expect to see a lot of sorry looking half-bullets floating around in my drink.
Can you use these Ice Cubes to make Ice-T?
@#6: Water expands when it freezes.
Now if it will always expand to fill the entire mold, I dunno. Might end up with a bunch of 7/8 bullets or something.
I believe the bottom holds just enough water to fill all the bullets, just not in bullet shape. When you put the top on, it displaces the water from the flat portion and fills the upper half of the bullet molds with that water. (Look at the lower half of the mold, it’s got a lip around the edges. The top half is smaller, so it fits inside that lip.)
I think there are small holes in each upper half bullet mold, so it’ll let the air out, but not the water (due to surface tension).
I’d love to mess with a set, but not badly enough to actually buy one.. since it’s unlikely I’d want bullet ice cubes other than once.
I forgot to add… this seems like a prime way to make ice bullets to re-test the Mythbusters experiment. Hmmm… compressed air, a solenoid valve, short rifled barrel… no sir, not going to do it. Don’t want to be arrested!
If you look at the picture carefully, you’ll see that one half of the tray has is recessed with a lip, and the other half fits into this recess.
So if you fill the recessed half entirely and press the two halves together, the theory seems to be that water will fill both halves of the bullet mold, and excess water will squish out.
The potential for failure seems to revolve around how well the halves lock together, and whether you’ll get seams in the resulting bullets.
Obligatory mention of possible secondary (possibly sexual) uses for bullet shaped ice
Number One with a bullet.
As a practical use, these would also fit well into water bottles (though other trays do this cheaper)
Wasn’t there a famous locked-room mystery which involved the victim of the apparently impossible murder having been shot with a bullet of ice, which then melted away, leaving no evidence?
I just wanted to say that I picked up on the music reference in the post. Nice one!
This would go perfectly with that vodka in the bottle shaped like an ak-47
An ice bullet is also one of the lesser JFK assassination theories. Mythbusters did an episode on it; result: Busted.
I want to get these onto a flight and use them in my drink.
These would also go well with Bulleit bourbon.
HeatherB … why?
yes, ice as the weapon of choice – melts away, no prints, no rifling! However, let’s resist and desist.
The new definition of liquor and “shots” 😉
Ben from TheJunction
a good shape to choke on, don’t you think? THAT would be a good locked-room mystery: no gun either.
…ISTR come comic book plot – might have been a Batman story back when Batman was all about solving crime and not getting gangraped by the likes of Grant Morrisson – where people were getting killed but nobody could find tbe bullets because they were made of ice and were melting before the coroner could figure out what was going on.
…On the other hand, the question of whether the ice would survive the short journey through the mach-plus traverse, much less the actual heat produced by the explosive discharge of the gunpowder, begs explanation.
@ #21 Why not? Fun to cause a little bit of havoc. If they can give me hell for having a fountain pen why not bring on ice cubes that make them go cold and then look like the fools they are?
OK, my eyes may be playing tricks on me and I may be all wrong (which would explain why no one has previously made this observation) but those don’t look like AK-47 rounds to me. The 7.62×39 round has more taper, more neck, a gentler shoulder, a smaller diameter bullet relative to the cartridge, no belt, and a much smaller extractor groove.
For the record, I think the Mythbusters got it mostly wrong with their ice bullet episode but it would take way too long to explain why they got it wrong and how to make it work. I swear, I’m nearing retirement and when I finish my current career, I’m going to put aside a couple of weeks to bust the busters on this one.
Its a magazine and NOT a clip dammit!!!
Don’t take the picture of the resulting ice bullets too seriously — they look entirely like the output of some nice computer graphics program.. like a simulated look of the result! They got the index-of-refraction wrong and the picture looks more like glass bullets!
@acb.. the version I read the assassin used a frozen blood bullet. In fact, it went as far as to say that the blood is of the same blood type as the victim! ha ha ha.
It is NOT a clip. Girly boys who don’t understand weapons call them clips! A clip you wear in your hair or you use in an SKS to load individual rounds.
This is a MAGAZINE of AK-47 rounds made from ice.
It seems that all the people talking half bullets have forgotten that water EXPANDS as it freezes…
If all else fails in attempting to make ice “bullets” with this tray without air bubbles, one could submerge the entire thing before closing it.
Also, ice bullets would still need a real shell and powder to be fired, so there would indeed be evidence of a bullet being fired, even if the bullet itself could not be found. Probably also there would be some indication of powder on or in the victim.
Ok People this may be shaped like a bullet but could never be fired as these are shaped like the bullet plus the casing!
Silly people imagining you could actually fire this… that would never be the case.
who says gunpowder would have to be a propelling agent? CO2 might be a bit more feasible to propel such a projectile…hell, you could probably jam it down the barrel of a paint ball marker to get the job done…although i wouldn’t advise it for obvious moral/ethical reasons.
“Girly boys who don’t understand weapons…”
What about girly boys who post under the name “anonyomous”?
Yes, and the hamburgers you get a McDonalds are going to look just like they do in the commercials.
pwned by advertising.
“If all else fails in attempting to make ice ‘bullets’ with this tray without air bubbles, one could submerge the entire thing before closing it.”
If you’re talking about an “incomplete” bullet, then yes. If you’re talking about making it clear rather than full of little bubbles, then submersion won’t help. The cloudiness of most ice is a result of dissolved air and minerals. Using filtered water or (as the previously-linked instructable points out) double-boiling the water will result in clearer ice.
Hmm, looks suspiciously like something I’d use for a “soothing facial massage”. Do they make a ribbed model too?
water only expands about 10% as it turns to ice. 1/2 of a mold will not expand to fill the whole thing.
they only way to get clear ice is to run it past soemthing ice cold i.e metal “forks” that the water will freeze to – boiling and distilling water dont work as when you pour it in to the tray air gets disolved into the water when it splashed etc. – so liek i was saying the only way to get clear ice is with one of those ice machines
Solution to gravity: close the mold in a sink full of water.
Both distilled and boiled water are questionable, but good thoughts.
I saw a show on ice sculptures, and the crystal clear blocks they use are specially made.
The freezing vats for ice used in sculptures have rotation metal blades to agitate the water while the open air aluminum tanks chill the liquid.
When the ice freezes the air comes out of solution due to constant motion of the liquid, and this might be further improved by using distilled and boiled water.
The ice cubes would be worthless and unrecognizable as soon as they are put into a drink.
To get perfectly clear ice bullets –
1) Begin with distilled water (fewer dissolved impurities)
2) Double boil the water – boil, let cool, boil again, let cool. (released ‘most’ of the dissolved gases)
3) during freezing, agitate the water – a battery powered vibrator works well. (releases the last of the dissolved gases)
Now you have perfect ice bullets.
Small product is small. Not bigger then my hand and the ice bullets you create with it breaks easily and could choke you.
I dont see why this was advertised as a great product but anyone who purchased it thinking “This is the greatest product evar!” are going to be so depressed when they finally get it… especially if they ordered it from the other side of the world.
These things never fail to attract the firearms terminology purist (The “magazine/clip” folks).
While I try to use proper terminology in my discussions, I simply don’t see why some people get so uptight about it.
Maybe they are just trying to impress people they will likely never talk to on the internet again, let alone real life.
But since I’m here, I might as well point out that the tray makes ice “cartridges”, not bullets. The bullet is simply the part the is actually shot out the barrel, the cartridge is the entire unit containing bullet, case, powder, and primer.
Hypocracy? Nope. Just throwing a fact out there. Learn something new every day, right?
How do you fill both halves of the mold? Try closing the halves together under water. Pretty simple huh? Sometimes the answer is to not over think the problem , Stonerkato
I left my vibrator under the ice tray and it made clear ice
The “ice bullets” shown are not what the ice tray will make. The ice tray will make half-bullets. Those in the picture are probably glass for all we know. Photographers usually use fake cubes when taking pictures of ice for advertisements
I own one of these bad boys, and yes, it is possible to make clear ice. XZZY was right, the bottom half is filled to the brim, and the top half squeezes the water out of the flat areas, the gas escapes out of the holes.
agitating the liquid whilst freezes makesthe ice clear
