It's not unlikely that your grandparent used canning jars for their original purpose: canning. But here in the twenty-first-century kitchen, the hard-to-destroy, easy-to-seal jar has become valuable for many more purposes. We love it -- and not just because one of the most popular models is manufactured by aerospace pioneer Ball.
The jars are cheaply available by the dozen, and replacement lids are even more cheaply available, so you can keep an array of lids on hand, customized for different purposes.
Here are a few of our favorite things to do with jars. What do you do with yours?
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

Personally, I try to distance myself from the sucky things of life. ;)
This article highlights one of those lost arts of days gone by that use to be so crucial to daily life. Canning in general is pretty useful but like duct tape, canning jars have infinite uses. I like articles like this that offer cool little DIY tricks for things I have around the house.
my roomate's aunt makes $83/hr on the laptop. She has been without work for 8 months but last month her pay was $8682 just working on the laptop for a few hours. Read more on this site...NuttyRich.com
I love these glass containers. I prefer them for use in bringing milk and juice to lunch each day. Easy to clean in the dishwasher.
Wish all the good stuff my mother used to can and preserve was in my kitchen.
Thank you for only posting ideas that are food stuffs.
To many people do stupid stuff like putting paint thinner in them and some kid or even an adult gets poisoned.
I hate spam, and spammers. Example: nutty rich
If you want to preserve mashed potatoes, you might try pulsed power methods that are used in the food processing industry. Such methods preserve the flavor because they do not use heat. They kill germs with powerful electric fields.
The technology is currently beyond reach of the home kitchen, but that can change. Here are some links:

personally I like to read articles which are at least 5 paragraphs :)
