Shotgun Shot

This is the easiest project yet. It requires a trip switch (see Freaky Swinger). But it is a tiny bit dangerous.

• 1 firecracker
• Any recording device
• The trip switch from the Freaky Swinger project

1. Set recording device to record.
2. Record the firecracker going off.
3. Set up so when trick-or-treaters step on the switch they hear the recording of the firecracker go off.
4. You're Done!
