If your child dreams of rockets, planets, and astronauts, an outer space birthday party is the perfect way to celebrate their big day. The best part? You don’t need NASA-level gear to pull it off—just some creativity and a few fun activities.
From DIY space birthday party activities for kids to simple games like scavenger hunts and piñatas, these ideas will keep little astronauts entertained from launch to landing. Here are 15 stellar outer space party games and activities your guests will love.
1. DIY Jet Pack Craft
Every astronaut needs a jet pack! Use empty soda bottles, spray paint them silver, add straps, and tuck red/yellow tissue paper on the bottom for fiery “flames.” This DIY jet pack space party craft gives kids something fun to make, wear, and show off—plus it doubles as a great photo prop.
2. Planet Ring Toss Game
Blow up balloons or use large balls as “planets” and let kids toss rings (glow bracelets are perfect!). This planet ring toss game for a space party is simple, budget-friendly, and doubles as fun party décor.
3. Galaxy Slime Station
Slime never goes out of style! Create batches of “galaxy slime” using glitter, food coloring, and star-shaped confetti. Kids will have a blast mixing and squishing their creations. It’s a little messy, but moms love it because it doubles as both an activity and a party favor.
4. Astronaut Obstacle Course
Turn your backyard into an astronaut training camp. Use cones, pool noodles, and hula hoops for crawling and jumping challenges. This astronaut obstacle course birthday idea burns energy, builds excitement, and makes kids feel like real explorers preparing for a mission.
5. Intergalactic Scavenger Hunt
Make a list of hidden space-themed items (toy rockets, glow stars, alien figures) for kids to find. This intergalactic scavenger hunt idea encourages teamwork, imagination, and exploration—perfect for keeping kids engaged during the party.
6. Solar System Bowling Game
Paint foam balls as planets and use them as bowling pins. Kids can roll a “meteor” ball to knock them down. This solar system bowling game combines learning with play, helping kids name planets while having fun.
7. Space Piñata Full of Meteor Candy
Nothing says party like a piñata. Choose a rocket, star, or UFO-shaped design and fill it with “meteor candy” (rock candy, chocolate balls, or starburst). Kids will have a blast taking turns trying to break it open—it’s always a highlight!
8. UFO Frisbee Toss
Set up hula hoops or cardboard cutouts shaped like planets and let kids toss ufo spacecraft themed frisbees through them for points in a competitive match. This game is budget-friendly, easy to set up outdoors, and perfect for burning off energy.
9. Planet Cupcake Decorating Station
Set out cupcakes, vibrant-colored frosting, and star sprinkles so kids can create edible works of art. This DIY cupcake decorating activity is fun, hands-on, and delicious—kids get their dessert and an activity rolled into one.
10. Rocket Launch Craft Station
Kids can decorate paper rockets and use straws or small launchers to blast them off. This decorate-your-own water bottle rocket craft is hands-on and thrilling—kids love testing whose rocket can fly the farthest.
11. Outer Space Bingo Game
Kids (and parents!) love bingo. Print an outer space bingo game featuring rockets, astronauts, and planets. Hand out small prizes like glow sticks or star-shaped stickers. It’s organized fun and a great way to calm the energy before cake time. The pictured bingo set is available as an instant download here.
12. Alien Face Painting Station
Set up a little station for kids to become aliens, astronauts, or even stars with face paint. You can DIY with stencils or hire a painter. This activity doubles as entertainment and gives kids a fun “souvenir” to enjoy all day.
13. Galaxy Spin Art
Set up a spin art station with washable paint in galaxy colors (purple, blue, black, silver). Let kids drip paint onto spinning paper to create their own galaxy masterpieces. It’s messy fun that produces frame-worthy art to take home.
14. Rocket Relay Race
Split kids into teams and have them run a relay while carrying a foam rocket or balloon rocket ship. The first team to complete the mission wins! This game is simple to set up, encourages teamwork, and gives kids a way to burn off some energy.
15. Alien Freeze Tag
Pick one child as the “alien” who tags others to freeze them in place. Friends can unfreeze by crawling under their legs. This game is fast, fun, and works great for bigger groups of kids who love to run around.
