this is the party popper bomb. I'm not shore if it works but I will post a video of it going off!
8 party poppers
Step 1: Step 1
to start off with is pulling apart 8 party poppers like so. I used a pair of pliers to get the explosive charge out.
Cut the string of the charges and get some masking tape and lay the party popper charges half a centre meter apart from each other. I'm only using two party popper charges because I only have 2 party poppers available.
Now get your sparkler and place it top end first onto the masking tape like so then wrap it up in the masking tape.
and your done!!!
