SLOW marble race ideas?? HELPP!!!!?

ok for my science class in school, we have to construct a roller coaster type thing inside a shoe box.. but the catch is, the winner is the slowest one. we must have an entrance hole and an exit hole, and we cant touch the marble after it goes in.





we get extra points for creativity, so i need some creative ideas that can help me win :D :D


thanks!!

oh i did it in AG classes if she gives you tape and a roll just cut the roll in half and slightly slant it up with the straw and then on the way make speed bumps with the traw
Reply:Coat your track with honey. It's sticky and will slow the marble down. Or you could build your ramps out of marshmallows or Peeps cut in half.
