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

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.
