Things You'll Need
Instructions
Find a flat surface, preferably concrete, and clear away any debris or obstructions to form a blast zone with at least a 10-foot radius. If recording with a video camera, position the device opposite of where your safety position will be. Place the car that will be destroyed on the blast surface and use the camera to zoom in on the car.
Use a "blast shield" to prevent shrapnel injury from the explosion. A small overturned table works best. If working with others, make sure they have their own shields or that your shield is large enough to accommodate more than one person. Wear safety gear like goggles and earplugs.
To increase the realism of the explosion, use lighter fluid for more fire. Use only one to two squirts of the fluid on the inside of the car. The type of explosion you want determines where to set the explosives. Placing a firecracker in the car will create an outward explosion; placing them underneath will lift the car skyward. Set your firecrackers accordingly.
Make sure the fuses are straight to ensure ignition. Begin recording or have an assistant do so before seeking shelter. Light using the matches or lighter, then run quickly behind the blast shield. Most M-80 and M-60 fuses burn at a 30-second rate, allowing ample time for escape. After the explosion, extinguish any flames by covering the wreckage with the damp towel and stop recording with the camera to repeat the setup process for additional cars if desired.
