Critical Thinking Bulletin Board

Here is just a quick bulletin board I put up at the beginning of the year. All you need is some construction paper and tissue paper to make this one work. I kind of think I should have added more fire towards the top. What do you think? What do you think this rebus says? Ideas?

If I had more time to make this board at the beginning of the year, I would have added white Christmas lights behind the tissue paper to add a flickering effect to the fire.

Have you figured out what the board says yet?

SET THE WORLD ON FIRE–great back to school theme!
