Get a cardboard box and cut the top flap off. Fill the open box with marbles. Get a long piece of cardboard and place it over the opening (a piece of scotch tape place losely over the top can assist in temporarily keeping this lid in place). Put the box on a cupboard shelf with the open end facing out. Close the cupboard door and pull out the cardboard piece you were using as the temporary lid.

When your mark goes to open the cupboard door, the marbles will spill out all over the place! Make sure there are no breakables under the cupboard for the falling marbles to damage.

We've heard this prank before but with ping-pong balls. All the fun with less risk of smashing up counters, floors and other breakables with falling marbles.
