Well I am only 12 and in elementary and were doing this thing called an egg drop where you have to invent something that will save the egg from breaking/cracking when we drop it. My idea is A baby shoe with some thing soft inside and place the egg in the shoe and tied to it is a balloon that can't flow up but down.(the balloon is for the invention to flow down softly/slowly. Pleasse do not suggest new ideas just ideas to add to my "already thought of" experiment. PLEAASSE HELP!

Sounds good to me.
The two things you're trying to do are control the rate of descent and the impact of the egg.
The helium filled balloon will slow the descent, and the padded baby shoe will cushion the egg.
Make sure you try it ahead of time. It will take a big helium balloon to slow the shoe/egg assembly.
I'd recommend one of those mylar balloons they sell at the grocery store. Those also don't leak anywhere near as fast as a latex balloon. If you fill a latex balloon the night before, it may be "dead" by the time school starts in the morning.

The baby shoe will give very minimal padding, and you can assess the lift power of the balloon by comparing, with your hands, the lift the balloon generates against the weight of the egg/shoe. Your typical mylar helium balloon is too small to do much, and adding more doesn't help much as the balloons themselves are relatively heavy. You would need a pretty big one.
Also maybe if you put the baby shoe inside a box about the size of a basketball with lots of padding.. but then the balloon will be even less effective.
Sorry but this idea is an egg-breaker.

As suggested earlier the baby shoe padding would be insufficient. Would suggest bubble wrap as additional padding. Now you havent mentioned if the balloon is lighter than air (meaning filled with hydrogen/helium), if so add more balloons. If not try arranging several balloons in a protective shell manner and try to keep the show-bubblewrap-egg in the center of that arrangement. If the balloons dont burst, the egg should survive.

returned in seventh grade ( many some years in the past,lol) I had to do the egg drop to and you had to have atleast 50% of the egg showing additionally, no parachutes etc. What I did replaced into so common and it replaced into certainly between the few that survived the egg drop!! Make a dough out of water and flour and positioned it right into a plastic cup and then stick the egg on the precise and push it 0.5 way down.... once you drop it it would land upright simply by fact cups are larger on the backside so theres extra weight and the dough could soak up the ask your self of the drop and the egg will in simple terms drop down slightly into the dough... attempt it out some situations at abode with the consistency of the dough and make confident the dough doesnt dry out till now the drop... good luck and that i'm hoping it works out for you :)

I know you said no new ideas but. . .I can't resist.
I'm thinking about whether you could use jello gelatin. Prepare the gelatin and pour half in a container, let it set. Place the egg in, pour the second half and let it set. The jello will both protect the egg, and when the container hits the ground, the egg will deaccellerate at a rate that will not break it (hopefully).
Maybe jello can be the cushion inside the shoe?

Try and keep the weight of your cushioning device as low as possible and the size of your balloon(s) as big as you can. This will slow the impact down.
As with any design project, test it as soon as you can so that you can update your design. That way on the big day, you will know exactly what will happen.
