The dicey-ness of college campuses and other living arrangements you may have while not being on the Fortune 500 list prompted us to create a post where you can learn how to secure your stuff. Diversion safes are oldies-but-goodies and are one of the best tricks to provide quality protection while maintaining a discreet look (not to mention a cheap way to guard your stuff). So here’s how to make one.
What you’ll need:
Quick-setting Epoxy
Plaster of Paris (available at craft stores)
Soup can, shaving cream can, can of beans…basically any discreet can that you can make sure remains undisturbed
Plastic jar with threaded lid that is smaller than your can
SIDE-CUTTING can opener (ABSOLUTELY muct be side-cutting. Even though this is about being cheap, don’t cheap out on this step)
Cash or other valuables to be place in your new safe

First, after acquiring your tools, open the bottom of the can with the side-cutting opener. Leave the top intact and take off the new lid from the bottom.
Second, clean out the can. Do whatever necessary to remove the can’s previous contents. Eat it, throw it down the garbage disposal, give it to your dog; whatever works for you. Rinse it out to ensure proper cleanliness and dry with a paper towel. Try not to get the label wet.
Third, mix up epoxy and put a glob-sized amount on the inside of the metal lid. Put the small plastic jar with the lid upside-down on top of the epoxy in the lid and center. Spin around the jar on the lid to make sure the small lid has the same center point as the can’s lid. Let the epoxy dry. If you did it right, the plastic jar should fit inside the can.
Fourth, mix up Plaster of Paris. You need enough to cover about an inch of the jar inside the can and its better if it’s a little watery. Pour the Plaster inside the upside-down can. Push the jar into the can while applying pressure to ensure contact. Two-four minutes later, after Plaster starts to set, unscrew the lid a half to a full turn and push some more to make sure it’s super snug next time you screw the metal lid on. Allow 20-30 minutes to solidify.
Fifth, use it. That’s right, you’re done. Put cash or other valubles into the jar inside the can and screw the lid back on. If you wish (actually if you’re just neurotic), you can sand the sides of the can where you cut the lid to make sure you don’t get a boo-boo.

LAZY WAY: This is not recommended, since the chances are someone will attempt to drink from the can revealing your secret. Hey, college students are desperate. They mooch off their friends like you wouldn’t believe. Since soda cans are two pieces, you can simply cut off the top of one and store your stuff in it. Only top-access though, and again, it’s not the safest option. You should probably use some gross can of something that no one will touch, like some nasty fish by-product. This will save you from any unnecessary break-ins. You’re welcome.
