A sparkler bomb is a Sparkler bomb there isn't really any way to describe it.
Materials:
10or12 sparklers
2 lids of of 2l pop bottles
drill or nail
duct tape

Construction :
Take all the sparklers except one and crush them up into dust. Then drill a hole in the tob of one of the lids and put a sparkler in for a fuse. Take the sparkler dust and fill up the lid without the hole in it then put the lids together and tape them up with duct tape. Now just light sparkler and step back. These are fun and relatively safe.
