Turn an empty jar into a cutting-edge vessel that challenges established aesthetic conventions.

This project has gotten such an overwhelming response maybe it should become a whole new website. Unfortunately "" isn't available.

Step 1: Scratch the Surface

Dip the end of your glass cutter in oil before scoring the jar. Use a tuna can or other object to keep it at the right height. Don't roll back over the old cut or you'll blunt your cutting wheel. No one has actually ever resisted the urge to do this, so this glass cutter is horrible.

Step 2: Beat on the damn thing

You know, to get that crack to break off cleanly

Step 3: Harder and Harder Until it Breaks

A real scientist would have done it with baking soda and vinegar.

Step 4: Sure it's Beautiful, But Does it Work?

The intrepid Will Bosworth tests out this cutting-edge vessel.
Great art is not just to be looked at, but experienced with all the senses.

When you've got a broken jar you really like, rub the sharp edges with sandpaper til they're rounded off and don't cut you.

Excited to learn more about broken jars?

I suggest cutting the glass with heat.

His first sentence.... Turn an empty jar into a cutting-edge vessel that challenges established aesthetic conventions. The last sentence of the actual instructions... When you've got a broken jar you really like, rub the sharp edges with sandpaper til they're rounded off and don't cut you. He considers this an art project. You have to read more than just the title before you comment, please.

LOL I love the jar "hit it till it busts" it would be easier to just drop it on the cement

I can't believe the oh-so-great TimAnderson would make something this horrible! ( No offense )

in the second photo he swallowed a peice of glass. This is the crapiest instructable ever.
NO DUH!!! That's why it was in the "Worst. Instructables. Ever." Group. Did you expect it to be the best in the world?
Look at the guy who made this, why dont you...
This is actually the first thing from this guy that I saw. So... yeah!

u could just put the top of the bottle in hot water, then put it under cold water. it's a lot easier
what is the almighty point of this?
what is the sound of one hand clapping? point of this. there is no point to anything!
Sounds kinda like a flat tire in a bugs bunny cartoon.

While it doesn't suit my particular aesthetic taste, I like that you made something that brings up the subject and asks the question of what beauty really is. Very nice, +1 :).
it must dribble horribly, artistic or odd, iono, but unpractical fosho. it does make everything seem more... iono. post modern i guess.

also, perhaps tap it from the inside. tapping on the side of the score confuses the glass!

I've had mixed luck with the string and fire method... but I was looking for an awesome way to not have to buy a bottle cutter. But the can as a smooth support is brilliant. I'm going to use a taller can for cutting a wine bottle!

yeah.... I agree with motorsk8ter- just throw the dang jar on the ground
Or slam your jar into your head.

Never done it myself, but I've been told that heating the score line over a flame will cause it to pop at the score line.

I laughed so hard and for so long at this instructable that my fiancee put on headphones. It's just That Good.

First of all this looked nice until the 3rd step, it was actually looking cool but then it crapped up. If you look at the second picture on the last step you see that he swallowed a peice of the glass, it's funny and ironic. The glass got it's revenge. Second of all VG CATS FOREVER!!
how did he swallow glass?

It's a metaphor for American foreign policy.

You know, it started out as one thing, and then it changed, and now it's all broken and someone's drinking out of it, and the broken shards are laying all over place, and could cut anyone at any time.

Which really sounds a lot like a relationship. And the only thing to do is just make the best of it, and not get too hung up on any one thing, and try to keep those glass spears from jabbing you in the eyes when you're you're really thirsty and tired and would like to blame someone else, except there you are messing with all this broken glass for no reason.
And it worked fine, as a drinking vessel, before you broke it, just a little uncomfortable if you have a big nose. Imagine your nose cartilage after your relationship changed/jar broke!
