I prolly just shot a gun cuz it was hard to screw up! That sounds like I could screw that up real nice like, Jim!
Closest we ever got to electricity was the big ball that created static electricity and it went thru everyones hand around the room....that was pretty cool!
Im just glad I didnt kill myself when I installed the 200amp service in the barn here. No experience at all...installed meter box, load center, and 6 circuits! Passed rough in and final...I guess im not so accident prone these days!

The secret with the egg drop..be careful to not make the padding too soft...or too hard. A lot of kids messed up not taking that into consideration. I used really light pillow stuffing as my top layer to soften the blow..and then I think I used insulation, and newspaper, and then collapsible pieces of cardboard. That way when the egg made contact, there were other materials that would slow it down before it reached the bottom of the box...and then the bottom of the box was spring loaded.
There were also other kids who made theirs too "bouncy" and the eggs would just bounce out and smash on the concrete.
wonder if thats how they design crumple zones?

It doesn't matter how hard or soft my interior padding is really. As long as there isn't any wiggle room between the egg and the padding it'll be ok.
Here's a drawing.
The idea is that when the box hits the rubber bands will stretch to absorb the impact. As long as the egg doesn't move around in its inner box it can't get smashed. The only problem will be making sure the bands are strong enough and making sure they don't bottom out. The whole box is dropped. The egg isn't dropped into a catching device.
Once I have it put together I can test it from 50+ feet in dad's manlift. It's only a 3rd story window it gets dropped out of for the test.

The only concern with surgical tubing is that I don't want to make a sling shot. I want to make a cushioning device.

Cris started talking about her kids doing stuff in a science fair. Lisa got to talking about egg drops.
Next year or year after I have to do an egg drop for Physics.
My design is a smaller box suspended inside a larger box by surgical tubing or rubber bands or something with the egg placed inside the smaller box. The stretchy stuff would absorb the impact so the egg could survive.
We're discussing the ways it can be done and Lisa is telling me I should be an engineer.

Oh yeah thats cool. Engineering is cool, except for the schooling part of it! I had a good buddy that was taking that at a college here, and they had to do a bunch of useless crap too!
Kinda funny, i ended up doing half of his projects for him, he had some good ideas, but it seemed like I was always able to one up him!
That would be a cool career though for sure Pete.

I don't think it's as cool as you might think it would be.
Civil Engineering consists of a lot of arguing with wetlands commissions and all that garbage.
My uncle is a civil engineer. They offered him the job of town engineer for his town. He told them no thanks he couldn't afford the pay cut right then.
The good news is that civil engineers don't spend all day inside. They can write off their mileage because they're constantly driving around checking on jobs they designed and they make 6 figures.

Ok. That sounds like that would work a lot better because one concern I had was that the rubber bands wouldn't be strong enough and that they might break on impact. The surgical tubing would be easier to get the exact right length on as well.
The only concern with surgical tubing is that I don't want to make a sling shot. I want to make a cushioning device.

It can be glued with rubbber cement also.

Yep...thats the dang thing! I dont think he turned it on until we all held hands...
Good thing too, if I wouldve seen something like that theres no way I wouldve put my hand on it!
