take a disposable camera once u have used the wholerole of film u can activate the flash. Wait until the flash light is on. then smash the bottom of the camera on the ground the flash will go off... the next part is the best. what you do is set off the flash towards you and keep looking at one spot. after your eyes adjust, you can see what it all looked like as the flash went off. trippy the light fantastic indeed.(if u are to stupid to realize that the lights are supposed to be off then u should not try this trick)
