Every mad scientist needs jars and those jars need labels, and since I like to reuse my jars the jar labels would need to be re-writable. Luckily, making re-writable labels for glass jars is easy with chalkboard paint.
Enough talk, let's make some chalkboard paint jars!
All you need to make your own chalkboard paint jars is chalkboard paint, painter's tape, and chalk. Not only will your jars be quickly relabeled, you'll easily be able to distinguish between your coffee beans,marshmallows, dried monkey brains, and whatever else you have stored in your jars. You'll have the cutest jars for your lab this side of the Bride of Frankenstein.
