The goals of the project are:To make an egg-carrying deviceMake it cost efficientMake it safe for the eggMake it float in waterMake it fast when it fallsMake it accurate when it fallsMake it be able to withstand the power of a medicine ballStep 2 Research the ProblemThe parachute had several designs made by different kinds of people such as Leonardo da Vinci (who used the weight of the jumper) or Jean-Pierre Blanchard (who focused on the safety limits).

Fact: The word parachute was made by combining the two words para- and chutePara means Defense against while chute was French for Fall.

Designed by Fausto Veranzio Step 2Research the problemThe Wright Brothers came up with the designs of many planes and gliders and made many improvements. This led from wooden airplanes to high-powered biplanes.

Step 3develop possible solutionsThe egg could be held in a carton cell and placed in a Styrofoam cup. A Styrofoam bowl could act as a roof to prevent the egg from falling out, it would taped from the inside of the bowl to the inside of the cup. Also, a trash bag parachute to slow it down during the air challenge.

Step 3develop possible solutionsRubber bands can take a large amount of force. So we could cut out the bottom of the cup and glue 5-6 rubber bands both sides of the bottom of the cup.

Step 3develop possible solutionsThe egg could be held in place buy string on all sides. Also, a wooden base could protect the egg from the air challenge and water challenge; it will also help the device float.

Step 4pick the best possible solutionWe decided to go with these design ideas:

Styrofoam Cup with a Styrofoam Bowl over itTrash bag parachuteWooden baseRubber bands to cushion the blow in the air challenge

Procedure:Place an egg carton cell inside of a cup. (on the bottom)Tape the egg carton cell to the cup from the indie of the cup with duct tape.Place a Styrofoam cup on top of a Styrofoam bowl.Tape the Styrofoam cup to the Styrofoam bowl from the inside of the cup with duct tape.Cut out a hole out of the bottom of the cup.Stretch a rubber band tightly and on both sides of the cup and glue both sides of the rubber bands tot the cup.

Step 5Create a PROTOTYPE Procedure (cont.):Repeat step 6 four more times and cover the entire bottom of the cup with stretched rubber bands.Stretch another rubber band tightly and hold it down to the cup the opposite two directions you did with the first 3 rubber bandsCut 2 pieces of the wooden plank and make the length of them be 3 inches.Tape the 2 pieces of 3 inch wood together at the center of both wooden planks. Tape them all of the way around.Cut two more pieces of wood and make the length of them be 1 inch.Cut two more pieces of wood and make the length of them inches.

Step 5Create a prototypeProcedure (cont.):Glue the 2 1 inch wooden planks to the two wooden planks that are taped. Glue them right next to where you taped the wooden planks. Do this on both sides of the tape.Glue the two inch wooden planks onto the two 1 inch wooden planks. Glue the two inch wooden planks on the inside of the two 1 wooden planks. (The inside is the closest to the tape)Glue the two inch wooden planks to the bottom of the cup.Tape the trash bag to the cup by placing tape on opposite sides of the cup and opposite sides of the trash bag

Isometric DrawingStep 6test and evaluateWater ChallengeGoals:Make the vehicle float for 2 minutesKeep the egg safe

Step 6Test and EvaluateWater ChallengeResults:SankFloated for 1.60 seconds

Step 6Test and evaluateAir ChallengeGoals:Make the vehicle land as close to a target as possibleMake the vehicle as fast a possible Prevent the egg from cracking

Step 6Test and evaluateAir ChallengeResults:Landed 0.51 meters from the targetFell to the ground in 1.59 seconds (avg. speed-15.66m/s)Egg cracked

Step 6Test and evaluateLand ChallengeGoals:Keep the egg from crackingPrevent the device from breaking

Step 6Test and EvaluateLand ChallengeResults:Egg did not crackDevice broke
