Egg Drop Design Challenge: Straws, Index Cards and Hot Glue

Click For Summary
SUMMARY

The Egg Drop Design Challenge requires participants to create a contraption using only plastic drinking straws, index cards, and hot glue, with a maximum width of 4x4 inches. The design must include a door and prioritize lightweight construction for optimal scoring. A suggested design involves cutting the straws to 4 inches, assembling them horizontally into a block, and using index cards as stabilizing fins to prevent flipping during descent.

PREREQUISITES
  • Understanding of basic physics principles related to gravity and impact.
  • Familiarity with structural design concepts, particularly in lightweight materials.
  • Basic crafting skills, including cutting and gluing materials.
  • Knowledge of aerodynamics to enhance stability during the drop.
NEXT STEPS
  • Research techniques for lightweight structural design using straws.
  • Explore methods for creating stabilizing fins with index cards.
  • Learn about the physics of free fall and impact forces.
  • Investigate previous successful egg drop designs for inspiration.
USEFUL FOR

Students participating in physics projects, educators teaching principles of engineering and design, and anyone interested in practical applications of physics concepts.

Hi, I have to make the classic egg drop contraption but we're only allowed to use plastic drinking straws, index cards, and hot glue.
the width also has to be smaller than 4x4 inches but it can be as tall as we want it to be (but preferably small)
and it has to have a door of some sort?
Anyone have any ideas for the design?
thanks!

Did you read the 135 existing threads (I counted) on egg drops? If not, that's a good start. If so, what ideas did that give you that you have questions about?
 
Will you donate part of your prize to PF if you win? :-p

Hi, sorry I didn't check yet
But i'll check it right away!
Thanks for the tip :)

Haha I wish
But it's just a project for physics class :/

We can use as many as we want

That’s too easy.

The thing is that the smaller and lighter it is, we get more points.
and the whole thing can't have a bigger width than 4x4inch which is pretty small...

Cut the straws to 4inch and glue them like this:

You can build a tall 4x4x... block with the straws horizontal. Cut a round hole on top of the block for the egg. Use the cards as fins to stabilize it flight, so it doesn't flip.
