Things You'll Need
Instructions
Place the flashlight lens-down on a piece of poster board. Card stock or paperboard can be used in place of poster board. Trace an outline of the head of the flashlight on the poster board. Set the flashlight aside.
Draw the desired constellation or star arrangement on the piece of poster board with the stars inside the traced circle.
Punch out the stars using the tip of a pencil or a long-necked craft punch. Cut out the circle along the traced line.
Repeat Steps 1 through 3 to create a variety of constellations and star arrangements. Experiment with moons, comets and other astrological bodies, if desired.
Tape one of the punched-out poster board circles to the lens of the flashlight. Don't cover any of the punched holes with tape. Turn on the flashlight and point the beam at the tent ceiling. Simulated stars will appear on the ceiling.
