**Final Design Build Draft**

** Explanation ** The problem was I had to make a marble fall slower from two feet up. My solution was to make a design to make the marble fall slower. First you drop the marble into the tube. Next you watch the marble goes down the zigzag garden tube. After you watch the marble goes in the swirl garden tube. See how long it took for the marble to go down. ** Materials ** I need 5 ½ feet of garden hose, 1 marble, 1 paper bag cut in two,duct tape, and a stopwatch, a dictionary, and duct tape. ** Why is it the best solution? ** I think it is the best solution because I have materials that slow the marble down while it goes down, the design and the jump makes it take longer because it is in the air not on the ground.
