You never know when you will need Batman’s help. That’s why it’s handy to have this batarang keychain from ThinkGeek at your side. The perfectly portable beacon sends out the call for help with just the push of a button. You can project the symbol into the sky or just against a wall in your office. I recommend saving it for dire situations, but I won’t judge if you use it because someone stole your smartphone or you can’t find your way to the toilet in the middle of the night.
See the Bat-Signal keychain in action after the break.
