NOPE!!! Good explosions are all about containment. Those 3 Liter plastic bottles can hold a lot of pressure before they blow. If you ever jammed one under your car tire and ran over it you'd know what I'm talking about. A plastic bag wouldn't hold much pressure, it would blow up but would fizzle. On the other hand, a heavy duty plastic bottle will explode pretty violently. One new year's eve I filled a 3 liter bottle and put a fuse in it. My youngest son (who was a dare devil) asked if he could take it out into the field across the street from our house and lite it. I told him that it would be OK with me as long as he lit the fuse and ran as fast as possible back to me. He said "OK". I gave him the lighter and he disappeared into the night across the field. We all saw the lighter flame in the darkness as he lit the fuse then we could see the fuse burning. I waited and waited but my son never showed back up. The damn thing exploded and lit up the whole neighborhood and shook the windows. After the explosion my son finally showed up laughing like hell. He was pumped up with adrenaline. I looked down at his leg and noticed a lot of blood coming from his calf. When I checked out his calf I found a large chunk of plastic buried in his calf. I had to use a pair of pliers to pull it out, it was buried pretty deep. He never felt the plastic enter his calf (too excited). But he surely winched when I pulled the chuck of plastic out of his leg!!! I asked him why it took so long for him to get back to us after he lit the fuse
. He said that after he lit the fuse he dropped the lighter and in the dark he had a hard time finding it as the fuse burned away. He said that he finally found the lighter and started to run away when the bottle exploded. I consider myself lucky that my son got far enough away to only get a shrapnel wound.
