Egg Drop Competition

I'm having an Egg Drop Competition, and I'm wondering if my plan would work

The restrictions are
1. Cannot be Bigger than 4inx4in
2. Must be able to let egg survive a 2 story drop onto concrete
3. No parachutes
4. The Contraption must withstand being stood upon
5. No commercial packing devices

Currently my plan is to use a non Newtonian fluid to suspend the egg in a zip lock bag and probably use a toilet paper roll to insure that the egg falls end first, to maximize the surviving power of the egg. However, I'm having a hard time figuring out how to withstand the force of a 150 pound guy standing on top of it.

Any suggestions?

Titanium box.

Would something like a 4x4 square plexi-glass box with a liquid inside of it work? Or some sort of foam inside?
 
well my egg drop thing I made was had to be smaller then 10x10x10, any how I used a box put springs on the bottem and some on the sides sides. I had cotton on the inside and, I tested it from 3 story drop, well it survived. But on the day of the competition, the teacher was on a roof of a one story building and threw it up in the air doing a barrel roll, well it landed upside down were there were no springs, I was quite mad. I even made sure if I threw it up straight in the air that it will fall flat on all the springs.

And the person that won made a parachute lol. It was suppose to be an moon lander thingy, and I argued that you cant use parachutes in space that you can with springs.

pvc pipe section? then glue a plug in the bottom.

Fill the space between the egg and the pipe with insulation foam or fix-a-flat.


Or...or...or...

Leave the egg inside the hen and chuck that off the building.

oh my. I haven't actually laughed at an ATOT post in a while.

:laugh:
 
you might want something that is shear thinning as opposed to newtonian. water is quite accessible though. and of course, the best way to check is to test it out 🙂

also, toothpaste is a bingham fluid (requires an initial shear stress for flow). may want to look into that, too 🙂
 
Problem with most of the suggestions is that they either do not conform to the 4x4 limit, or they cannot withstand a person standing on it.
 
To allow someone to stand on it, you need a frame of some sort. Whatever you use to protect the egg needs to insert into this frame.

You could easily just use a coffee can, fill is with some sand, put the egg, fill in the rest with sand up to the edge, put the lid on. Wrap in duct tape to keep the lid on. Egg will survive several falls.

Can withstand 150 lbs of force?

I weigh 200 lbs and just stood on my peanut butter jar. It did not budge. This was standing on the lid, not the side of course.

For a reference, I have used a jar of peanut butter for an egg drop competition and it worked flawlessly.

Titanium shell, like JLee said, egg suspended by wire mesh inside, surrounded by thick non-Newtonian fluid (I think ballistic gelatin would work). Would be under 4x4.
If titanium isn't readily available or too expensive, steel would work fine. Construct outside like they do black boxes, and it will survive 150 lb man standing on it.
