You show a can with a lid on. Removing the lid, a lit match is dropped in.
Fire shoots out proving that the can contains some highly inflammable object.
You immediately cover the can with a lid putting off the fire.

After a few moments, when the lid is removed, it is found to be filled with colorful items!
You produce silks, spring flowers etc. from it.
After some production, tip the can over a tumbler and water pours down.
When you have emptied the Can, you again produce articles like paper currency, ribbons etc.
Then pour water from the can!!
