Glowing Constellations Space Science Experiment
In this fun and easy space science experiment, we’re going to show you how to make glow in the dark constellations to investigate and explore.
IMPORTANT: THIS EXPERIMENT IS NOT EDIBLE – DO NOT CONSUME
Materials:
- Marshmallows
- Toothpicks
- Glow-In-The-Dark paint
- Zip close baggies
- Chalk
- Black construction paper
- Wax paper
Instructions:
- Sketch out your favorite constellation with your chalk on the black construction paper. You can also print out an image of a constellation online and use this is your blueprint.
- Determine how many stars are in your constellation.
- Put that number of marshmallows “stars” in the baggie.
- In a separate bowl, mix a few squirts of glow-in-the-dark paint with small amounts of water until the paint becomes watery.
- Pour the paint and water solution into the baggie with the marshmallows.
- Gently work the marshmallows around until they are covered in paint. Try not to smash the marshmallows.
- Place the marshmallows on the wax paper to dry.
- Once completely dry, use your constellation sketch or printout to build your constellation by connecting the marshmallows with toothpicks.
- Once complete, take your new constellation into a dark area to enjoy or use a black light to really intensify the glow. You may also hang it from something with a piece of string.

How it Works:
The toothpicks are used to hold the marshmallows in position to represent the constellations as we see them from Earth. The glow in the dark paint is used to make marshmallows glow to represent stars in the night sky.
Make This A Science Project:
This is essentially a STEM activity utilizing engineering. Try building other building, bridges, or structures with the toothpicks and marshmallows.
