The Disposable Archimedes Cube





Introduction: The Disposable Archimedes Cube

About: Hello! I like to fix people who are broken. Sometimes it works.

Ice cubes are easy to make! But then they're a pain to get out of the tray, and bump against your upper lip while you're drinking, and make you sad thinking about the Titanic, if it were in the drink. 

I wanted to make a new ice cube, one that wouldn't make you weep into your drink for all those lost souls as tears rolled down your frostbitten upper lip into whatever you happen to be drinking.

I succeeded! With the help of...ARCHIMEDES.

Step 1: The Raw Material

FIRST: Fill a plastic cup with just a little bit of water. 

This water will someday be your Disposable Archimedes Cube!

I haven't tested it, but I suspect if you use a glass cup, you may shatter something along the way.

Step 2: Put a Glass on It!

That's right...a SECOND plastic cup. No, really...hear me out.


Fill this second glass with enough water to displace the water in your original glass to the level you want the ice cube to be.

I guess you could fill it with gold if you wanted to be classic about it.

Step 4: Freeze It Like Walt Disney's Head!

Just like that. The ice in the first cup will expand, pushing the first glass upward using some sort of Scientific Force.

Now you may remove the second cup from the first. If you have used plastic, as the instructions stipulate, this will be easy. If you've used glass there will be little shards of glass mixed in with your Archimedes Cube and you will drink bitter sorrow.

Bonus! The ice cube from the second cup can be given to someone less cool than you. It is a fully functional ice cube.

Step 5: Fill With Liquid Victory!

Advantages to the Disposable Archimedes Cube: 

--It will not bump against your lip, freezing it
--It will cool your drink circumferentially, maximizing surface cooling area
--It will melt evenly
--It will stabilize your plastic cup, preventing the "overstrong grip spill leak" faux pas

Disadvantages to the Disposable Archimedes Cube:

--None. It is a perfect Platonic form and you may dream of it tonight.

    Excellent idea, thanks, saved to my "must try one day" list.

    Alternative: take the second glass out, put another, empty, glass in, then fill that with drink - the liquid will be cooled by contact with the ice but not diluted as it melts? And the second glass can have another, empty, glass in it as well

    lol I think it's limited by how many glasses one oould get upright in a freezer - might be neat to have a short series of shaped ice - maybe have a contest and the loser gets the plain-ice one that was at the top

    i'm going to do this RIGHT NOW bec we have an "ice issue" in this house (ice cubes + 5-1/2yr old = Not A Good Thing and many wet socks)

    I have the same problem. Except mainly because my dexterity is roughly equivalent to that of an especially clumsy 5 1/2 year old.

    My heart is filled with gladness and relief. While I can not be sure to dream of your icy magnificence this night, those dreams shall undoubtedly be enjoyable. I raise my suddenly old fashioned glass to you!

    Really?!? Or just store real glasses in the freezer and forego "cubes" completely. Better for the environment, saves water and doesn't dilute drinks.

    Indeed--the overuse of water via wanton ice cube consumption is not just our problem, but one for our children too.

    And this is why I usually (and selflessly, for the children) just drink straight from the bottle.

    My next instructable will have to be on how to get acquitted on a public indecency charge.

    Unfortunately, he did. There are blurry photos of the event in the local paper. It was a sad day. Quite sad for Luke, actually, as the blurry bit was rather tiny.

    No, I tried it with gold and it melted the thin cup and ran into the floorboard cracks. Darn!

    Boy am I late to this party! Is Scientific Force one of the Fantastic Four?

    Great Instructable, sir!

    Your instructions are hilarious. Love it.

    This Instructable is way to cool to keep a secret! I am sharing with all my friends... Wait, I haven't any, yet.

    Anyway, I was wondering if this would work with several layers of cups instead of just two, and using the deep freezer to accommodate the volume and stack of cups? Can't wait to give it a try. Thanks a lot!

    I have friends. I also have a girlfriend. My girlfriend thinks I'm a stalker: well, she's not my girlfriend yet.

    *Not really. I happily married, but the joke's too good to pass up!
