Physics4U Egg Drop Contest

A photo of Beejeong Beejeong
Design a container to protect an egg when dropped.
Materials cost no more than $5
Dimensions do not exceed 30cm x 30cm x 30cm
Mass limit is 150g

Any ideas for a design?

What kind of material could absorb the impact of hitting the ground?
I'm trying to think in more of a physics aspect.

I suppose a parachute is out of the question? :P

Just make an egg shape in Styrofoam (2 pieces that fit together) and make sure it's snug. And maybe add some air resistance (wings) if you're dropping the egg from a really high point.
Eggs are actually pretty strong, just make sure it lands vertically and there's something to cushion the fall and it shouldn't break.

I would recommend a container, with something like styrofoam and something soft inside, and covered in asphalt sealant.

I did that with straws...how high is the egg going to be dropped from?

Is weight going to be a factor? Often the weight is measured for the winners (likely will be a few who drop safely). If so, this idea is even better.

Put the egg in a toilet paper roll (minus the toilet paper) and attach "wings" at the top of the tube. Jam a little bit of soft material at the bottom just to be safe.

Only about 3-4 meters.

i rmb doing something like this back in grade 9
my partner and i spent countless hours on it but in the end it failed
and another student spend maybe 10 mins on it and his worked perfectly D:
the trick is to make yours light; maximize surface area to create air resistance
make a parachute if possible or add wings thus causing it to FLOAT down not drop down

We did this in my class, except we fired the egg containers out of potato cannons instead of dropping them! It was hard, because our capsule had to be less than 3 inches in diameter or else it wouldn't fit in the cannon. :P

I think I used a parachute to orient the craft to fall in the correct position, and then used a combination of styrofoam cups and water balloons to make a crumple/impact zone. The egg was in a carboard container situated above the impact zone.

Put the egg in a container full of jello? (I'm not sure if this will work). :p

I remember a group of people at my school last year and their design won. They ran one leg of a pair of tights through the box length wise placed the egg in the middle (within the tights) then ran the other leg through the box width wise and somehow got it around the egg again.

They way they had it set up they could throw it hard at the ground and it never broke.

Get a loaf of bread. Remove half the bread. Dig a hole in the bread for the egg. Place remaining bread in the bag. Fill bag with air. Seal bag.

Ooh, I was also thinking of using pantyhose somehow. Did it look something like...

I just drew that in paint lol.

I think this one would be really light cause all it would need is an empty box and a pantyhose. :)
And why thank you. XD

I did this in grade 11. It has to hold 2 eggs and mine was a cup insoled with memory foam where my first egg could sit. The other egg was outside the top of the cup covered in a dome of memory foam. I also had a parachute which was used to slow the falling speed of the vehicle, and also ensure the cup would land upright as it had foam on the bottom aswell. It was only 46g and it withstood a toss from 3 stories.

Aside from dropping the egg from a 3 meter height,
a 25 pound weight will also be dropped on to the egg from a 3 meter height.

That's a tough one to accomplish.
Dropping the egg seems easy, and I think I have a lot of ideas, but the 25lb weight dropping on my egg? That's literally impossible..
[size=8]
Any ideas?[/size]

Also remember the weight must not exceed 150g, and dimensions must be less than 30x30x30cm.

Does the egg have to be in the same container for the drop and smash (can't fix it up a little)?

LOL I did this last year in Physics 11..
Hardest thing ever, only one group was successful.
Use lots of straws, paper, and tape to cushion your egg for the drop.
Be very creative with the design.. don't just do a cone or box like the majority of us did.
