While there are many successful egg drop designs, one of the most successful is a conical design. With 20 straws, a roll of Scotch tape and some thought, a conical egg drop can be created in no time.Continue Reading
The shape of any egg drop design is crucial to its success. The shell of an egg is actually structurally sound, as an arch is the strongest geometrical structure. The goal of any design is to use the natural strength of the egg by diverting energy around the entire surface. Cone shapes are often the most successful, and a cone shape with a strong point can be created from 20 straws and a roll of Scotch tape.
To ensure the force of the impact is properly diverted, the egg drop needs to be designed to fall the right way. With a conical design, it is important to add some stabilization so the egg falls point down. Layers of Scotch tape can be combined to create fins for stabilization. Add these to the wide end of a conical design to encourage it to fall point down.
As with any experiment, test the design before any competition. Make multiple egg drops, and test them at varying heights to determine the success of the design.
Successful egg drop design methods include soft landing features such as parachutes, shock absorbers such as balloons, and counterbalance mechanisms. NASA has also created an egg drop design resembling the Mars Pathfinder landing gear.Full Answer >
The source of the name "egg roll" is unknown. Spring rolls, the Chinese snack upon which egg rolls are based, do not contain eggs in the wrapping or filling. The name may come from an unrelated Chinese dish in which a filling is rolled up in a small omelet. The American egg roll wrapper contains a small amount of egg, so that may be the source of the name.Full Answer >
Remove sticky Scotch tape residue by applying nail polish remover or petroleum jelly to sticky areas and then wiping with a paper towel or damp cloth. Remove duct tape residue by applying WD-40 or lighter fluid to the area and then wiping it off.Full Answer >
To build a rabbit cage, cut six panels from a roll of wire mesh, clip them together, attach a drop tray, cut a doorway in the front panel, and attach the door. This two-hour project requires a roll of 18-inch wire mesh, a sheet of wire floor mesh, wire cutters, a drop tray and hinge covers.Full Answer >
