Galaxy-Themed Birthday Party: Activities and Games

Often, kids go to the birthday party for games and entertainment.

The delicious food and cake seem to remain in the background for them.

But when it comes to the scenery, the atmosphere, that’s the real magic.

Here are some great galaxy-themed birthday party activities, and games.

Crafting

Little kids just loved to play with glue, pencils, and really enjoy crafting.

Simply prepare a craft-store area where they can find stars, planets, and space ships for each of them to decorate with paint, glitter, and stickers.

This is a great way to keep them busy, and even inspire them to make their own room decoration.

Paintball

Organizing an open-air galaxy-themed birthday party? What is better than a galaxy paintball game.

You can turn regular paintball kits into powerful galaxy weapons.

Use galaxy-themed birthday party masks or create DIY vests to divide the guests into teams.

Coloring

You can find tons of free printables with a space, astronaut, stars, and planets theme. Place a few activity tables with crayons in galaxy-decorated boxes.

Of course, you can always purchase special space-themed coloring books that can be doubled up as a party activity and make a small gift for each little guest.

Movies

If your party guests are old enough for a full feature film, you can set up a home theatre in the living room, patio, or basement.

Classics like the early Star Wars episodes, Close Encounters of the Third Kind, 2001: A Space Odyssey, or even selected episodes of the Flash Gordon TV series are perfect for your galaxy-themed birthday party.

Just in case make sure the movies are suitable for the age range of your guests.

In case on your galaxy-themed birthday party, you are expecting just little ones, you can find online short space-themed cartoons or made-for-children educational videos about the solar system.

Some of the recent space adventure ones like Star Wars: The Clone Wars (animated) or Zathura are also suitable for youngers.

For really younger children, offer animated feature films like Mars Needs Moms, Space Chimps, Space Buddies, or Wall-E.

Stargazing Campfire

Having a simple campfire-style cookout with hot dogs, sandwiches, and s’mores is a great way to celebrate your galaxy-themed birthday party.

You can prepare printouts of the different constellations for the youngsters to search for and spot these in the night sky!
