ok, I'm having a egg drop contest soon and i need some ideas!
parachutes ARE aloud, the only rule is: no ballons and the egg cannot be modified. and the drop is two stories

heres my idea, build a regular mushroom like parachute with holes in the back to propel the egg foward. use a balsa wood box renforced with steel rod to carry the egg. i will use med. density foam for cushoning. I'm gonna use some foam airplane wheels and make a tripod design wheel base, my hope is that the parachute propels the egg foward then once it lands it will roll. and i want to set up a suspension design on the back wheels, i will put the rod connecting the two wheels together in a straw, then glue the straw to low density foam, and glue the foam to the box, then use large U shaped staples to hold the axel (straw) in place. what do you think? i was also thinking of using a tube with a spring in side to cushion the egg.
 
Can you use springy wire for the axles? If so then you could make an A shape for the wheel base which inherently provides suspension.
 
If I was to do this I think I would find or make a firm frame in the shape of a ball with a small plastic container suspended in the middle by a couple rubber bands as a shock absorber.

The container would be for the egg and you could wrap the egg in foam for added cushion.

That design with a parachute should be a winner!

Then again, that sounds like a winner as well!:hehe:

i did this to like two years ago.....i built a lil box then suspended the egg in the middle with rubber bands then built like a four foot parashute with a garbage bag and it worked perfect..i also had a bunch of foam and stuff in the middle...

Egg cannot be modified? What does this mean? I'm guessing that they've been clued in to wrapping the egg in several layers of electrical tape and just dropping it like that, which will work with no problem.
 
i like alpines idea. they didnt say you couldn't drop someone with the egg

I just tested Alpine's theory, but I used a fat old guy since I couldn't find a fat kid on such short notice.
I did it off the 6th floor fire escape, so I might have had a problem with excessive velocity.
The egg was not intact when the paramedics arrived. I'm not sure if he crushed it during a moment of sheer terror or if the excessive decibel level of his screaming on the way down caused it to explode.
I've since started a rumor that he seemed very depressed lately.

:ahem: :sick:

Thats y u use a fat KID, the old ones are too wrinkley and flabby and just splat, while the younger more taught skinned ones bounce and all of the kinetic energy is displaced through the ass (assious maximus) instead of the fragile egg shell (babius makerus protectorus).

Oh man Rolex...that made me laugh good.....you are so wrong....cough cough...ok back on topic I will do a bit of thinking....I did one as a kid and it did pretty good. It was molded in a bock of extra firm jello in a small box, with a parachute as well. On the parachute remember you NEED a small hole in the top of the canopy to allow air to escape and that is what helps the chute stay stabilized.

put it in a bag with a thick non-newtonian liquid, like cornstarch and water. You'll be amazed how much impact it can absorb. You may have to play around with the viscosity to get it right.
 
Very odd indeed, but we seem to be having a rash of jumpers today.
The end result is that the egg will survive going off the 3rd floor if it has been swallowed whole by a fat kid.

Seriously, the egg made it. :celebrate:
I read that in the autopsy report.

ok, i got the prototype parachute done today, and the basket. i tried several designs and this one works the best. its cardboard on the bottom and grocery bag on the top. if i plan on using this, ill make it larger and use several layers of garbage bag.

oh, and Rolex, do you think my neighbors annoying fat pug will work?

Well if he's annoying enough who cares if the egg survives. :D
 
Not nearly enough fat to body mass ratio to use a Pug. Just enough to save him, but not the egg. I'm being sued for his vet bills. I think he landed on his face, but It's hard to tell if there's new damage.
 
Well I tried something...the neighbor lady that hates RCs so bad agreed to go down her stairs head first. However the experiment was a total failure. I forgot the egg. So I am going to try it again with an egg this time.....as soon as the retraining order is lifted.
 
sit the egg in a r/c with realy heave shocks so it doesn't bottom out..(might want to put the egg in some foam first)...then tie a big a$$ parachute to the r/c and drop the r/c over....
