Constellation Light

Bring the beauty of the night sky indoors with this fun and enthralling DIY constellation light! It’s a great way to encourage kids to explore the stars and fuel their fascination with space. Plus you can have them trace their favorite star patterns from our Constellation Dot2Dot Printable, then play a game of “spot the constellation” once the light is set up in a dark room.

How to Make a Constellation Light

Step one: Measure the jar’s height and circumference. Apply the same measurements to a piece of foil and cut. (Younger kids will need an adult to cut the foil.)

Step two: Pick your favorite constellations from the printable to draw on the foil. After drawing with a pencil, use a Phillips-head screwdriver to poke a hole to mark every point in each constellation. Then use a safety pin to poke small and big holes all over the foil to create a field of stars. If doing this activity with younger children, adults should make the holes.
