Bat Signal
Materials:
1. Flashlight
2. Sticky Note/Notepad
3. Black-inked Pen
4. Scissors
5. Tape
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.
Color and Paste
Color in your bat black, then cut it out and put tape overtop of it.
Final Step
Paste the tape overtop your flashlight and turn it on. This only works when the flashlight is really close to the wall.
