Have you ever wondered how to make a marshmallow gun, a duct tape wallet, or a levitating book shelf? If you answered yes to any of the above then instructables.com is the place to go! There are more DIY projects here than you can tackle in one summer and user comments to go along with them. The site offers user generated instructions on all sorts of projects, including some that you probably don't want to try at home. I'd be a little bit concerned about anything that involves fire or fire propellants, particularly if you have children and/or you value your home. You can avoid these projects by staying out of the 'not liable' category. The instructions are very visual so if you are that type of learner you'll have a field day, but because they are user generated the results may vary. You can usually tell which ones might give you trouble by reading the comments of those who have attempted them before you. I'd recommend skimming through the comments before you attempt your project anyway, they often include nice upgrades.
Now, you'll have to excuse me, I'm off to build me an office supply trebuchet!
