Question egg catcher

hi, i'm new and don't know how to do this forum stuff, anyway i would like help w/ my physics project. We are required to drop an egg (w/o a surrounding container) from increasing heights and we must build a contraption out of flat toothpicks and glue to catch an egg from free fall. we're not allowed to make glue webs (strings of glue that would catch the egg), turn the toothpics into dust to catch the egg, have random toothpicks to slow down the falling egg, and all parts of the contraption must be uniform. Any sugguestions of this design would be of help.

Dear Wellington

When a space shuttle is entering the earth’s atmosphere, its nose must be towards down 6 degrees (more less) in order to be able to enter and not to bounce back to space.

If you want to build a contraption, just have in mind that a part of it must have an inclined wall (like 6 degrees from vertical axe) and then another wall that follows tah one but at 8 degrees…and so on so that you can cushion the impact of the egg and the help him stop by increasing friction (with the angle of the wall) between the egg and the wood (toothpicks) and the make a stop at the end.

Hope this helps you to have an idea for your design

Best regards

Oscar Ramírez

hmmmmmmmmmmmm.... maybe this would work.... If you made a base out of toothpicks, apply the glue, stick more toothpicks pretty close together, and drop the egg. Maybe it will stop in the cradle of toothpicks... or even better! stick glue on the side of the standing toothpicks and see if the egg will stick! Tell me if it works!

Unhappy egg projectile

Remember: The greater the surface area, the more Bernoulli's Principle will act, and will slow down your projectile. If you built a large platform of toothpicks, it MUST have more mass than your egg, or it will flip and be a falling target.

Toothpick platform


*hope you liked my diagram!*

It doesn't NEED cushioning if it's floating down, like a feather.

Yours truly,
