2 empty plastic soda bottles
White spray paint
Silver holographic fabric
Holographic tape or ribbon
Cardboard box (for the pack base)
Pink flexible fidget tubes
Pink plastic stars
Hot glue gun

For the Rocket Flames:

Step 1: Create the Astronaut Suit
Start with a shiny jumpsuit or metallic leggings and a matching top. A pastel iridescent fabric works beautifully to give it a magical touch.
Add a pink ribbon belt around the waist to break up the metallics and add a girly pop of color.
Attach star patches or cut stars from pink felt and glue or sew them onto the chest and sleeves.
✨ Pro Tip: If you don’t want to sew, fabric glue works perfectly!
Step 2: Make the Astronaut Helmet
Use a large clear globe or bubble as the helmet base.
Cut lavender craft foam strips to create the framing around the helmet. Secure with hot glue or silver duct tape.
Line the bottom with holographic cardstock or silver tape to give it that NASA-inspired look, but with sparkle!
✨ Optional: Add small star stickers or patches for extra shimmer.
Step 3: Build the Jetpack
Spray paint two empty soda bottles silver (or wrap them in metallic paper).
Decorate the bottles with strips of holographic tape and small pink felt stars.
Attach the bottles side by side onto a cardboard box wrapped in silver paper. This forms the jetpack base.
Glue pink bendy straws or tubing into the top of the bottles for fun “oxygen hoses.”
Attach pink backpack straps (ribbon or elastic) so your child can wear it easily.
✨ Want extra glow? Add battery-operated LED lights inside the bottles!
Step 4: Add Rocket Flames
Cut flame shapes from pink, lavender, and silver felt. Layer them together to create a “shooting flame” look.
Glue the flames into the bottom opening of the soda bottles.
Let them dangle freely for movement while your little astronaut blasts off into space!
Step 5: Final Touches
Put on the sparkly suit, belt, and helmet.
Strap on the jetpack.
Add silver gloves or holographic boots if you have them.
And just like that—you’ve created the most adorable pastel astronaut costume ever!
