🎮 Activities & Games
Plan 3–4 structured activities and always have a backup. Start with a calm warm-up activity as guests arrive, then build energy, and wind down before food.
Build a cardboard rocket ship
Supply large cardboard boxes, duct tape, aluminum foil, and markers. Teams work together to build and decorate a rocket — perfect for photo ops after.
Alien freeze dance
Play space-themed electronic music and have kids dance in slow-motion like they are on the moon. When the music stops, they freeze in an alien pose.
Moon rock hunt
Spray-paint rocks silver and gold, hide them around the party area, and give each astronaut a collection bag. Write point values on the bottom of each rock.
Galaxy slime making station
Pre-measure glue, liquid starch, and glitter in cups. Kids mix ingredients and add food coloring to create custom galaxy slime — provide zip bags for transport home.
Planet ring toss
Stack balls of increasing size on cones and have kids toss hula hoops to ring the planets. Label each ball with a planet name and award points by distance.
🎨 Decorations
Focus on the entrance and the food/cake table — those are the two areas guests photograph most. Dollar store supplies and DIY touches save money while looking great.
Starry night backdrop
Hanging planets and stars
Silver and blue balloon galaxy
Astronaut cutouts
LED fairy lights as stars
🍰 Food & Treats
Keep food simple and finger-friendly — especially for younger kids. Prepare or order food before the party so you can focus on activities and guests.
Planet cake with rings
Rocket ship cookies
Alien cupcakes
Moon cheese and crackers
Galaxy punch with dry ice effect
🎁 Party Favors
Budget $2–$4 per guest for favors. Pre-pack favor bags the night before so handout is quick and stress-free at pickup time.

Space figurine sets
Galaxy bouncy balls
Astronaut ice cream
