Hello I was being my dark dumb side yesterday and made a dry ice bomb... I rapped it in duct and sealed the lid and rapped that in duct tape... then I threw it. I didn't seal it well so I waited 3 min. and went and got it and as I was sealing the expected happened. BOOOOOOM... easily loudest sound ever heard. Couldn't hear for around 30 seconds and my wrist is slightly sprained... How many of you have done this?
