I wonder if you concentrate Dark Side energy into a 2 inch Star Wars Darth Vader Helmet PVC Keychain that it will be dense enough to trap light and create its own event horizon! Black Holes come from the Dark Side right? I should probably work on my astrophysics. Still the Star Wars Darth Vader Helmet PVC Keychain is freaking awesome for us Star Wars fan! A black and white PVC keychain made to look exactly like Darth Vaders rather imposing helmet this keychain will make sure that the Death Star is fully operational by the time the Emperor arrives.
