"The pit is completely enclosed. And it's full of leathery objects, like eggs or something." -Kane (Alien)
Is a simple idea. I have some left over ballons, newspaper, flower and water. what cah I possibly make. Just an AWESOME alien egg. Now, what your going to need is-
Duct tape- found around house
Flour and Water- sink and shelf
now that you have that, put in the movie ALIENS and have fun.
