The cast of Uphill Down - 1997 includes: Rebecca Eddy as Deidre Melissa Kavanagh as Kate Robert Loring as Bobby Andrew Sarno as Arthur

Then light another match, hold it tip down and time how long it takes the flame to move halfway up the stick. Be careful not to burn yourself!uphill, for an experiment look for "Do forest fires move faster uphill or down hill
