I am trying to build a parachute (not life size, but for a project) and just wondering what are your suggestions to create a parachute that will carry a load of 40grams as slow as possible to the target.

My idea is to use a main big parachute holding enough air to really increase the time for it to drop with many small little parachutes attached to the side. You think this would be the best?

What would be the best material?

Nylon...

Don't know how big..

You just want loft with no control correct?

Its a minature parashoot carrying a 40g (imagine a film canister filled with rice and a twoonie) load from 2-3 story high.

I dont think there are any way of controlling it but the object is to hit the target with the slowest possible speed.

What I've red is circular is slower than rectangular shaped parachutes and that greater surface area = greater time to fall.

is there a limit on how big your parachute can be? use nylon for the cloth and that fishing line stuff for the string, if there's no limit on how large the parachute can be just make it as big as possible and then test it and make adjustments.... lol or just ask someone who's in engineering here! lol

If it can fit through a door, so basically if there are no braces than I can fold it up, nylon great but will that alter the accuracy of landing on a point? I want a design to land straight down or fairly close, its being dropped 3 levels high down to the floor inside the school (so low / minimal wind) and it is to hit the target or close.
