An outer space birthday party is a stellar way to ignite the imaginations of young space enthusiasts! With astronauts, rockets, and twinkling stars, this theme is perfect for little adventurers. If you’re looking to create an out-of-this-world experience, these 25 ideas will help you launch a party that’s truly cosmic.
1. Outer Space Invitations
Start the party on a high note with invitations that feature astronauts, planets and other space-themed designs to set the tone for the upcoming birthday.
2. Rocket Relay Race
Set up a relay race where kids carry a small toy rocket or spaceship as a baton. Add “space-themed” obstacles like jumping over craters (hula hoops) or crawling through tunnels to make it extra fun.
3. Alien Slime Station
Provide ingredients for kids to make their own alien slime using glitter and green, blue, or purple coloring. This a great activity because it also doubles as a unique party favor that the kids can take home. Here’s a link to an Elmer’s Glue slime kit on Amazon if you’re looking for an easy way to get it started.
4. Rocket Launch Station
Set up a play area with foam rockets or stomp launchers for kids to see who can shoot their rocket the highest. Rockets that include a parachute that deploys on the way down are great because it gives the kids a chance to try to catch their rocket before touchdown. Here’s a link to a rocket that includes a parachute.
5. Space-Themed Coloring Station
Provide coloring sheets featuring rockets, planets, and astronauts to keep little ones engaged. Larger coloring sheets that can be combined into one big picture after coloring all the separate parts is a great twist on the activity for older kids.
6. DIY Space Helmets
Provide each guest with a cardboard or plastic DIY astronaut helmet to wear during the party.
7. Planet Scavenger Hunt
Hide paper cutouts of planets around the yard or house, and give kids clues to find them. There could be a prize for whoever nabs the most planets if the group is up for a little competition.
8. Moon Walk Challenge
Lay out a path of pillows or mats and challenge kids to “walk on the moon” without touching the ground. This is great for helping to burn off some steam if the little astronauts are hyped up on space cake.
9. Alien Cupcakes
Bake cupcakes with green frosting and fondant shaped into eyes and antennas for a cute alien look.
10. Solar System Bowling
Turn bowling pins into planets and let kids “knock them out of orbit” with a small ball.
11. Alien Bean Bag Toss
Make a board with alien faces and cut out holes for the mouths. Let kids toss bean bags to “feed” the aliens.
12. Galaxy Balloons
Inflate black and silver balloons and speckle them with white paint to resemble stars and planets. Here’s a link to a collection of planet themed balloons available on Amazon.
13. Space-Themed Music
Play songs like Twinkle, Twinkle, Little Star for younger kids or space-themed movie soundtracks to set the mood of the party.
14. Rocket Ship Cake
Create a cake shaped like a rocket or decorate a classic cake with space-themed toppers like astronauts and stars. Ask a local bakery to help if you want to go all out and make a cake that stands out.
15. Space-Themed Piñata
A rocket ship or planet-shaped piñata filled with candy and small toys is sure to be a hit. Here’s a link to a custom rocket piñata that an Etsy seller makes.
16. Edible Moon Rocks
Serve rice cereal treats shaped into round “moon rocks” and coated with edible silver spray.
17. Cosmic Punch
Serve a punch with blue or purple juice and floating star-shaped ice cubes made from fruit juice.
18. Ceramic Painting
Order a set of plain white space-themed ceramics for party guests to paint and make their own. Aliens, astronauts and planets are great choices for the ceramics. These are also great party favors because guests have a personalized gift to take home with them after the birthday.
19. Glow Stick Galaxy Jars
Have kids create their own glow stick galaxy jars by filling small jars with water, glitter, and glow stick liquid (supervised by an adult).
20. Astronaut Training Obstacle Course
Design a simple obstacle course where kids can crawl through tunnels, jump over “craters,” and dodge “asteroids.”
21. Alien Face Painting
Hire a face painter or set up a DIY station where kids can become aliens, astronauts, or space explorers. This is a great opportunity to snap some fun photos for remembering the special day. Print off the photos before the end of the party to send the kids home with a personalized party favor of themselves.
22. Build a Spaceship
Use cardboard boxes, foil, and stickers to let kids construct their own mini rocket ships.
23. Astronaut Freeze-Dried Snacks
Include freeze-dried treats like ice cream or fruit to mimic astronaut food.
24. Space-Themed Party FavorGoodie Bags
Send kids home with goodie bags filled with items like mini rockets, alien stickers, and glow-in-the-dark stars.
25. Starry Night Projector
Set up a starry night projector to add an immersive celestial ambiance to any party area.
