The Mary Poppins bag effect

Hey Guys,

I have a shoot coming up this weekend and we were wanting to know what the best way to do the "pulling a very large object out of a small box" effect would be. Are there any tutorials out there?

It's too easy for a tutorial. You just need two identical bags and tables. Cut a hole in one bag and table. Attach bag to table. Show the good bag carried to the good table, show the bag getting placed on the table, switch for the trick bag/table, pull a large object up through the hole.

you just need to take the scene with somebody taking the big thing out of the bag and make sure you got a shot of the background.
then you mask the unwanted part under the bag in post and key the background inside the mask.
no green screen needed, but it is a lot easier with static scene.
