So I was thinking that you could make an ice mold shaped like a straight bong and a lid the seperate it into 7.5mm thick ice shaped like a straight bong also (It's easier to pull out as opposed to bubble or pyramid bong.). with a line in the mold thick enough for the bowl/showerhead diffuser downstem shaped mold to fit in as a slider. That way, if it drops, who cares? It's ice! Plus if someone's coming you can just smash it and say you spilled your drink, instead of rushing to hide it and being all suspicious. Plus, since it's made of Ice it'll cool down your smoke.
