Why not treat the kids to a fun birthday scavenger hunt too?

Space party decoration ideas

Make cardboard rocket ships and shuttle the kids to the front door when they arrive.

Get a large appliance box, like a refrigerator or stove. Spray paint it silver, inside and out. Let it dry.

Cut windows. Glue bottle caps and odds and ends on the inside to represent levers and knobs. Place it on a dolly outdoors. When your guests arrive at the curb, let kids climb into the “shuttle” and push them to the front door.

The ride will bring instant smiles, and make for great photo opportunities.

Drape your walls with discount fabric that is dark blue or black to represent space.

Make lights dim and use a black bulb in one lamp for an unusual glow. Get some glow-in-the-dark paint. Cut a large sponge into a star shape, and another into moon shapes. Stamp them on the fabric. If you like, cut out cardboard stars and get styrofoam craft spheres in assorted sizes.

Paint them and hang them from the ceiling with thread and thumbtacks.

Think about getting an inexpensive fog machine to make a misty planet surface.

Cover furniture with white sheets to look like the bumpy moon surface.

Set up a “space station” for kids to play with.

Drape a table with silvery fabric.

Pile all kinds of old or broken computer parts and electronic gadgets. They don’t have to be plugged in, it’s just for fun.

Kids will enjoy pounding on buttons, switching levers, and letting their imaginations lead them to the outskirts of the universe.

Space party food ideas

Think of tube foods that astronauts use.

Yogurt tubes, ices in plastic tubes, any freeze-dried or dehydrated foods, and juices in foil bags will all suffice.

Did you know you can buy astronaut ice cream?

Available at museums, science shops, and Amazon, in single-serving packages, this is the actual freeze-dried ice cream astronauts take into space. It doesn’t even need to be refrigerated. Kids will really enjoy the authentic treat.

Make cupcakes with gray, cratered frosting for “moon rocks.” Make “alien guts” by making green gelatin jigglers. Mix some green food dye with olive oil and brush it on pizzas so they can eat some of the moon’s “green cheese.”

Space themed party games

Put a spin on the old “pin the tail on the donkey” and play “pin the eye on the alien.”

Paint an alien shape onto a poster board (don’t worry if you’re not an artist; the stranger looking the better), and cut out eyes for the kids to try and pin (or tape) to it.

Or cheat and grab this pin the mask on the astronaut game instead!

A great word game is, “I’m going to the moon.”

In this game, the first person says, “I’m going to the moon, and I’m taking…” then names and items starting with the letter A. The next person in turn repeats what the first person says and is taking, then adds something that begins with the letter B.

Go around in a circle alphabetically, each child repeating all of the items that have been said and adding another. It gets harder and harder, as the list gets longer and longer.

Have fun while learning about the planet, with our free planet matching game printable. See who can match the planets first.

Pass the moon rock is a fun game that is like musical chairs.

All the kids sit in a circle. Have a rock that you painted with glow-in-the-dark paint.

Play music as the kids passes around the rock. Whoever is holding it when the music stops is out. The last child standing who avoids holding the rock is the winner.

Make alien masks out of large paper bags. Cut eye holes and provide the kids with markers, pipe cleaners, fabric material, glue, and other craft items to make their own alien masks.

Make alien slime

green alien slime

This recipe makes enough for about three children.

Ingredients:

  • 3/4 cup liquid starch
  • Disposable plastic container
  • Green food coloring
  • 1 bottle (7oz) white school glue
  • Plastic spoon
  • Zip-lock baggies

How to make alien slime:

  1. Place liquid starch into a plastic container. Stir in 8 drops of green food coloring.
  2. Pour in the glue, stirring constantly with the plastic spoon. The mixture will become ropey in texture.
  3. Knead the mixture with your hands until all of the starch is absorbed. Let it stand for 5 minutes.
  4. Turn the slime onto a smooth, clean surface. Knead it some more.
  5. Now the slime is ready to play with.
  6. Give each guest a zip-lock baggie to store the slime in.

Plutonian Freeze Ingredients:

  • 3 cup fruit pieces, frozen (strawberries, peaches, mixed fruit, etc)
  • 1 container (8oz) yogurt, of any flavor
  • 1 cup powdered sugar
  1. Place frozen fruit in a food processor’s container. Process the fruit, stopping to scrape the sides occasionally, until it is very finely chopped.
  2. Add yogurt and powdered sugar. Process the mixture until smooth.
  3. Serve immediately or store in the freezer until ready to eat. Scoop it with an ice cream scooper.

Space themed birthday cake

Prepare two flat cakes according to package directions. When cooled, put chocolate icing on top with Oreos smashed up in the icing to look like a planet’s surface.

Make little UFOs by baking two very small round cakes, using the package directions. To decorate them, cover each cake with chocolate icing and put little yellow dots of icing along the edges to make it look like UFO lights.

Make aliens by baking cupcakes with white cake mix according to package directions, but add enough drops of food coloring to turn the cake batter green.

Top each cupcake with green icing (white icing mixed with green food coloring) and on top of each alien insert two pieces of a pull-apart Twizzlers for the antennae and two black jelly beans for the alien eyes.

Space party favor ideas

Fill some party bags with space-like candies (pop rocks, Milky Way and Mars bars, starbursts), glow-in-the-dark star stickers, little alien toys, and key chains.

Goodie bags can include Mars Bars, Rock candy, Pop Rocks, Milky Way Bars, toy walkie-talkies, space stickers, glow in the dark wall decorations, alien figures, foam rocket ships, a space torch, and bubbles.
