White sweats, a paper-bag helmet with a taped flag patch, and silver duct-tape stripes down the arms. Twenty-five minutes, easy: a white sweatshirt and sweatpants, a big brown paper grocery bag, and silver duct tape. The flag patch is what sells it, so tape one on each shoulder like the real suits.

  3. Wrap two silver tape stripes around each sleeve.
  4. Wrap two silver tape stripes around each pant leg.
  5. Press the flag sticker onto the chest.
  6. Safety: Cut the face opening wide enough that vision and hearing stay clear. (CPSC Halloween safety tips)
  7. Pull on the white sweatshirt and sweatpants.
  8. Slip the bag over your head.
  9. Line up the face hole.
  10. Crimp the top with a strip of duct tape.

Common questions

What size paper bag fits a kid astronaut helmet?

A standard large brown grocery bag fits kids and most adults. For a toddler, use a small paper gift bag and cut the face opening to match their face.

How do you keep the paper bag helmet from slipping?

Crimp the top of the bag with a strip of duct tape so it holds its shape, and cut the face opening wide enough that it sits on the shoulders, not the head.
