Excellent idea Dizaster! The height of summer would be ideal, all the chocolate would be messy and melted.

Over time you might like to experiment with other materials.

A bucket of fish heads would be my own favourite or maybe some of those fire cracker snaps you throw on the floor to make a banging noise when your kids.

You could even engineer a vacuum cleaner full of maggots. Have the window wound down and when a car drives by stick aim it at the car and stick it on blow.

The fun you could have would be amazing.
