Problem StatementThe egg needs a cost efficient vehicle that will protect it during the air, water, and land challenges in the triathlon.

Air Research• Gravity pulls the
vehicle to the ground• Air resistance slows
the vehicle down while falling
• The parachute is what slows down the object so it doesn’t get damaged when it comes in contact with the ground

Land Research• Crumple zones
redirect, redistribute, and reduce the impact of a crash
• Airbags and seatbelts keep the passenger safe in a car crash
• Before automobiles people lived in cities so that everything they needed was close by

Water Research• Buoyancy is the upward
force that causes an object to float on a liquid
• In order for a boat to float it needs to be water tight
• Most modern ships are made of steel and are used for war, fishing, and shipping things

Materials
1 Pine Wood Piece- $21 Styrofoam Cup- $71 Styrofoam Bowl- $102 Feet of String- $81 Trash Bag- $106 Sheets of Newspaper- $61 Glue Stick- $51 Foot of Duct Tape- $5
Total- $53

Procedure• 1. Glue egg carton cell to the center of the bowl• 2. Surround the carton cell with newspaper for padding• 3. Place the cup on top of the bowl upside down • 4. Use duct tape to make a latch and hinge so the cup will
close over the bowl• 5. Cut the pine wood into 6 pieces that are 4 inches long• 6. Glue 2 of the planks to the bottom of the bowl to make
skis• 7. Cut the string into 3 8in long pieces • 8. Hole punch 3 holes evenly around both the bag and the
bowl• 9. Connect the strings to the bowl and bag for a parachute• 10. Finally glue 4 of the remaining wood planks equally
between the sides of the bowl for support

Redesign• Take off the wood on the sides
because it punctured the Styrofoam cup and would lower cost
• Balance out the base of the vehicle so that it will not tip when it is placed in the water
• Make the parachute smaller so that it will inflate better as it falls to the ground
