A comet is a chunk of ice, rock, and gas flying through space. When they get close to the sun, they heat up. We can see their glow and long tails. In this activity, you鈥檒l make your own comet that can fly around the room!

What you need:

  • Chopsticks or a popsicle stick
  • Metallic ribbon
  • Scissors
  • Tin foil

What to do:

  • Cut five pieces of ribbon: two long pieces, two medium pieces, and one short piece. If you want an extra long tail, make the long pieces about three feet in length.
  • Tie your ribbons around the end of your chopsticks or popsicle stick. If you want the ribbon to be as long as possible, tie the knot close to the edge of the ribbon.
  • Cut three pieces of tin foil so they鈥檙e roughly square shaped.
  • Hold the ribbon pieces off to one side and gather the tin foil around the end of the stick.
  • Form the tin foil into a ball while keeping the ribbon tail off to the side.
  • Repeat with two more sheets of tin foil. Gather it around and form it into a ball. If you want a bigger comet, add more tin foil!
  • Take your comet on a stick and fly it around the room!
