No pics of the bong ill give you a rough idea of how it was done. We used the bottom of an old bowling trophy and just taped it onto the bottom of a bong.
Then i got 3 gas stove lighters from the local $1 shop (the ones with the long necks). When ya dismantle these you have and electric sparky thing (technical term.lol) attached to two wires and a nice bendy tube for the gas. I had a lighter that used to light when its cap was open (works the opposite way from most lighters) so that was glued into place either upside down inside the trophy. The we drilled a hole through the bottom and glued a bit of plastic on the plunger of the lighter and poked it through the hole. Then using a hot glue gun we made a bendy pipe coming off the lighter that split into 3 ends. The we dismantled a few more lighters for their outlet nozzles which was stuffed into the end of each bendy pipe. Then we used 3 socket set heads (tiny ones) to put over the end of the pipes to protect the nozzles from getting to hot. The 3 socket-ed ends were then taped around the head of the bong. Then we stuffed some batteries in the bottom connected to the electronic sparky thing which was connected to on of the socketed heads (ya only need to light 1 for them all to catch). Then this was connected to a reverse micro switch (not all that easy to find.lol) which was attached to the inside bottom of the trophy (with a bit sticking out the bottom so that when it was down it was off). And to finish it off we demolished some kids toy space ship for its flashy lights and sound Fx as we still had a micro switch left over they went around the outside of the bong which was then covered in holograph laser tape .
Unfortunately the police destroyed it when i got busted. ...so they say
