Sorry if this has been asked before, but is the egg attached to the parachute, or is it inside a lander which is attached to a parachute?

You attach it to whatever you want to attach to.. The event is all about launch time of the egg. If the egg detaches from rocket, attach it to the egg or capsule (egg inside). Don't forget, the least weight you have hanging on parachute the better hang time. Eggs are about 60 grams, the whole rocket could be as much as 200 to 250 grams.

Correct, loft time of egg = X seconds, egg detaches for main rocket = add 3 seconds to loft time, egg survies the ride = add 15 seconds to loft time + detach. At Athens times were in the order of...loft time = 22 to 30 seconds plus 3 plus 15 seconds. Top scores were somewhere from 27 to 48 seconds total.

Has anyone faced the problem of the chute not opening due to the cold?

I don't see how the cold should prevent the chute from opening, no.

If your chute isn't opening, make sure it is free of moisture so it doesn't freeze together (though highly unlikely) and dust your chute with talcum powder before launch. Grounding your chute may also help, to reduce static. Look at this website :

I've just been assigned to help with this event and all I know is one of the people who's already been working on it apparently has issues with their parachute. Until I get together with them, what materials has everybody been using for the parachute? How big are they?

I recommend using a thin plastic material, like a trash bag. As far a size goes, make it as big as you can, but make sure it's not too big to deploy properly. Mine are 1 meter across.
