Summary
Fill in the blanks.
A candle flame on Earth is a long, pointy yellow flame . But a
candle burns differently in outer space. A candle flame there forms
a ball because of weak gravity . Fire needs oxygen, so a candle
flame must be lit on a spacecraft. The flame draws oxygen slowly
on a spacecraft. The fire burns slowly too . Carbon does not rise
in microgravity. Only the hydrogen in a candle flame reacts, so
that makes a candle flame in outer space blue .
