Marble-Drop Madness

Design Build Challenge #2

Release a marble onto a freestanding contraption of our own design located at the edge of our desk.

Materials

  • 14 straws
  • 10 toothpicks
  • 3 paper cups
  • 3 feet of masking tape
  • 1 round marble

Goal:

  • Build a "structure" starting at the edge of the desk
  • Use "structure" to make a marble to end up in a cup on the floor
  • Make the structure go as far as possible from the desk (used to determine score)

Rules:

  • Limited to given materials
  • Marble must end up in a cup positioned on the floor

Results:

  • Team Team created a structure that went 4 and 2/3 tiles
  • The marble made it into the cup and stayed in
  • We scored 1 point after ranking 1st place against other groups
Our design:
  • Placed two straws next to each other and tape them together on only one side
  • Tape the seven pairs together again only on one side
  • To make a more stable track for the marble we place a toothpick in between the straws at each place the seven pair were connected
  • Tape the three cups together bottom to bottom and then top to top
  • Cut the bottom out of the first two cups
  • Stick the 3 remaining toothpicks in the side of the first cup forming a tripod
  • Lastly tape the straws underneath the edge of the table and the cups to the floor




Clean-up Time!
