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!
