Hack Your Coffee Cup with a Magnetic Sleeve
Need a place to stash your Starbucks Venti Mocha Frappa-Something while you reach for your car keys, dial your phone, knock out a few push-ups, or whatever? No problem: Just stick it to the nearest light pole, newspaper box, car door, or other metal object.
Before you actually let go, however, make sure the cup is wearing a magnetic sleeve like the one described at Pop Up Lunch. And an ingenious idea it is, as it certainly beats putting your cup on the ground (where it will undoubtedly get kicked) or the roof of your car (where it will undoubtedly get forgotten).
Just one problem: The creator doesn't actually explain how to make one, other than to suggest "embedding some magnets" into a coffee cozy. Well, sure, easier said than done, right?
Maybe not. Here's my simple suggestion for whipping up your own magnetic cozy:
- Order a pack of 20mm rare-earth magnets from DealExtreme for $4.26 shipped (or the vendor of your choice).
- Grab a couple of the thinnest cardboard coffee sleeves you can find. Super-glue three of the magnets in a straight line, top to bottom, to the outside of one of the sleeves.
- When that dries, nestle the first sleeve inside the second one and glue them together. Presto: You've got a magnetic sleeve (with the magnets hidden inside) that should be strong enough to hold up a beverage. (Note I said "should be." You'll definitely want to experiment a bit -- preferably with water as opposed to hot coffee.)
