What is that? You have a bunch of friends coming over and no drinking glasses? Do you have any sodas or beer? Assuming you do not realize your friends can drink straight from those, lets make you a new glass.

Be warned, this is not a strong glass. It is a cool glass though :D

Step 1: What You Will Need

Item you will need

1 Can (any size, any type, whatever makes you feel good at night)
1 Can Opener (the cutting wheel gear type as shown in the picture)

Time Required: 1 minute + however long it takes to enjoy your beverage

Step 2: Empty the Can

Drink your beverage.

Feel free to pour it in a second container so you can enjoy it while making your glass.

Side note related to beer: Craft beer is moving toward cans as a way to better protect the beer from oxygen and sunlight. The problem is you still need to pour the beer into a glass to really appreciate the aromas that come with your sudsy beverage. If you are camping or just without proper glassware, try just opening the can and taking a large sip then removing the top as described below. That way you turn the can into a glass thus opening a path for your nose to smell the beer without having to bring extra glassware. When you are done, just recycle the can as you would have before. As always, be careful to watch for potential sharp edges.

Step 3: Clamp Down and Start Cutting

Lets cut the top off!!! Be careful not to mess up!
  • Attach your can opener with the blade coming down from above and the rotating gear on the outer edge of the top lip
  • Squeeze the handle
  • Start cutting!

Don't stop cutting till you reach the end. Trust me, it is totally worth the effort.

Step 4: Finish Cutting

Don't stop cutting until you get to the end. That point should look somewhat like this.

Be careful not to cut yourself, the edges can be sharp!

Step 5: Optional: Remove the Stuff That Fell Inside

Either you pulled the top off as you finished cutting it or it fell in… Assuming you are the latter (as seen in the image) then you should turn it upside down and remove the insides. If you have not done so, clean out the insides with some water now.

You might not have needed an explanation for this, but I included it just in case it was not obvious.

Step 6: Good Job!

Good thing you finished, that previous glass is dirty already!

Step 7: Try Out Your New Glass

<p>I like this instructable but was wondering about 2 things that I thought about while reading it. It would probably be possible to go a step further and 1. Find a drinking glass that would fit inside of it somehow and insulate it by filling in the space between the outside of the drinking glass and the inside of your Guinness can and 2. Is there any way to coat the outside of the Guinness can with something to make it more scratch resistant? Just a few thoughts and great instructable. Keep it up.</p>
<p>I was anticipating that you would weigh it down some how (pour something on the inside, or affix to the bottom). Then I thought about it, apart from how it feels, it is not like any of these would just fall over and break. You know? </p><p>Simple and pleasing, this instructable also counts as a life hack. Thanks for sharing! </p>
<p>Just don't knock the can over and you will be fine.</p>
You are right. While adding weight to the bottom could help make it feel better, it is not all that necessary for functionality. The center of mass is nearly the same as it was before so it would only be necessary if you regularly knock over cans when drinking from them.
<p>sugru the bottom similar to the base of a wine glass maybe?</p>
<p>Fill the base (underneath) with bluetack?</p>
Awsome idea, and it works great!
l did this 2 days ago, before reading this Instructable. Wanted to use the can to stand up craft paint brushes and wool dobbers that I use in leather dying. I have a no name cheap can opener that came with a cheap set of steak knifes, had it for 10+ years. It cut the top off with nothing but a few sharp pieces. Just like stated in the Instructable, so used my dremel with sanding tool and now all is smooth. Thanks
<p>All that hard work emptying those cans and my Pampered Chef can opener didn't work. What brand did you use. I have Guiness cans just like yours.</p>
<p>I ended up using an OXO opener in these instructions. I have successfully used other openers as well. Based on these comments it seems you have to get lucky with an opener that is just right.</p>
<p>I have had some success with those keychain-sized, miltitary/camping style, can openers, for cutting the tops out of aluminum cans. I previously upped some pictures of this, here:</p><p><a href="https://www.instructables.com/file/FRFMRD7GB0JQNFT/" rel="nofollow">https://www.instructables.com/file/FRFMRD7GB0JQNFT/</a></p><p><a href="https://www.instructables.com/file/FXUJ2R5GAPV8EDX/" rel="nofollow">https://www.instructables.com/file/FXUJ2R5GAPV8EDX/</a></p><p><a href="https://www.instructables.com/file/F25HCQ2GAPV8EDY/" rel="nofollow">https://www.instructables.com/file/F25HCQ2GAPV8EDY/</a></p><p>Sometimes this style of can opener is called &quot;<strong>P-38 can opener</strong>&quot;. Actually, there is a Wikipedia article for this, here:</p><p><a href="http://en.wikipedia.org/wiki/P-38_can_opener" rel="nofollow">http://en.wikipedia.org/wiki/P-38_can_opener</a></p>
<p>I don't know the brand off the top of my head so I will have to check later. It looks like the pampered chef can opener cuts horizontally from the outside edge rather than vertically from the inside edge. Is that the case? If so, that may be causing the problem. By cutting the inside edge, it leaves additional support around the upper lip of the can. If it were to cut the outside, it would be removing that material and leaving only a weak edge.</p><p>How is it not working exactly?</p>
<p>My opener left metal slivers on the cut edge, some which fell loose, and there are ground gear tooth marks with metal dust on the outside rim of my can.<br><br>My compliments to whichever can opener that it is that you use, looks beautiful!</p>
<p>No need for a can opener! These a fairly common novelty here in Mexico, they're done mostly by kids with no tools but the sidewalk, it takes some time but all you do is grind, well more just like rubbing it on the concrete sidewalk for a while, about 5-10 minutes and you're done, no hard edges or anything. Just give it a good wash before using them. </p>

<p>Those can openers are garbage. As far as I know, there is only one brand of can opener that makes a decent cut. It's made by Pampered Chef and it's too expensive, but it cuts sideways into the can top crimp, not down. There's no sharp edge. I can relid a can so that nothing leaks out; the lid fits securely back on the can. I use it to put leftovers in the refrigerator, slosh out residue with water, and drain liquid out. </p>
<p>Warning: this technique has a terrible danger: </p><p>Make sure you don't swallow the widget !</p>
<p>I'd assumed there would be some sort of cleanup of the edges on the inside?</p>
<p>Unless the can opener failed to cut properly, you should not need to clean the inner edges. </p><p>If it got caught and ripped part of the can, then you could bend that part of the can back with some pliers. </p><p>If it is bad enough that you are considering sandpaper, I would just throw the can away. The metal is so thin that if you are sanding it down to remove an edge, you would be risking sharpening it even more. </p>
<p>As a word of caution only use this for cold drinks, being thin metal it will conduct the heat of the drink straight to your lips unlike a ceramic cup which is cooler on the outside.</p><p>Did this as a kid once and it was a lesson quickly learned.</p><p>Nice instructable</p>
<p>I bet it took a 6pack to come up with this one :)</p>
<p>This one actually was actually the time in awhile I have done this. Guiness cans seem to fit my cutter just right. That being said, everytime I have done this since I have had a bad cut. Maybe I am destined for slight imperfections for the remainder of my days.</p>
<p>We used to do this a lot with Miller Lite cans and then use the lids to throw around. you want to make sure to open the can first even if you don't intend to pour it out because the lid will initially sink and then rise back to the top and if you open the can it's incredibly easy to pull it out. Sharp edges aren't a concern unless your can opener gets stuck; the can opener is designed to push the metal sides down. I've been doing this for around 5 years and have never cut myself (knock on wood)</p>
I kind of feel like I'd be the friend to hold this too tightly and ruin a cup
<p>They are easy to dent. Luckily they are easy to replace. </p>
Good job.,thanks for sharing!
sooooooo easy
Cool idea
<p>What about the sharp edges? I assume you want to get those off to not cut your lips..xD</p>
<p>You definitely want to be careful for sharp edges. </p><p>That being said, the can opener often cuts in such a way that it pinches the edge down leaving a remarkably smooth finish. This has varied between different cans and can openers so your experience may vary.</p>
