Magnets in Star Wars. You've got your seal on the trash compactor in A New Hope (Luke: Will you forget it? I already tried it. It's magnetically sealed!). The use of the magnetic harpoons from the snowspeeders to take down the AT-ATs on Hoth. Even Chewie's bowcaster uses magnetic acceleration.
These little magnets won't take down the Empire but they might help you hold down your own personal fort. This set of two magnets, shaped like Han Solo in carbonite and Slave 1, geek out whatever surface you put them on - your fridge, your locker, the Starkiller Base along with that thermal detonator.... The sky's the limit!
