30 years ago BC (before Chive) Todd had an idea. What if you could make a vase by attaching a neoprene magnet to a circular piece of cast aluminum and fitting a simple test tube in it? So he gave it a go. Then to make sure the magnets were strong enough he put the vase on fridge doors and slammed them shut- angry teenager style. Eventually the Magnetic Test Tubes were born. They’re perfect as vases. And for finding metal studs in your drywall ( Chive tick #46).
