Ever wondered what could be lurking in that locker at the end of the hallway, the one with no owner, but with a lock? Ever asked anybody that question? I'll show you, in this first Instructable of mine, how you can create the same effect, just for a few laughs, or to really spook somebody out.
Step 1: Record Your Voice
First of all, record your voice, on your phone, saying 'Let me out!' or some similar phrase. Make sure you say it loudly, so it can be heard through a locker. Name this file 'Let Me Out' or something similar. This may only work on some phones.
Step 2: Place Phone in Locker
Set your ringtone to maximum volume, with 'Let Me Out' as the tone. Unlock the locker, and keys in hand, place your phone in and lock it up.
Step 3: Call!
Go somewhere where you can see the locker, but not be seen, like in the doorway of a classroom or behind a pillar. Using somebody else's phone, call your phone when somebody is near the locker.
Step 4: More
The victim will hear something saying 'Let me out!'!
To have an even scarier effect, try using the evil laughter at the end of Michael Jackson's 'Thriller'.
If you have any suggestions or improvements, please list, as this is my first Instructable.
