Step 1: Materials:
2. Sticky Note/Notepad
3. Black-inked Pen
Step 2: Create Bat
Trace your flashlight's circumference around the notepad. Then draw or trace a bat inside the circle. In mine, i used the bat from the dark knight rises.
Step 3: Color And Paste
Color in your bat black, then cut it out and put tape overtop of it.
Step 4: Final Step
Paste the tape overtop your flashlight and turn it on. This only works when the flashlight is really close to the wall.
