I made a Coke Bottle Bong,..
It works pretty good !!
Scientists in Thailand and Wisconsin have found that it doesn't work pretty good.
For decades, marijuana consumers have debated whether using a bong, where smoke is pulled through water before inhalation, is any safer than inhaling smoke from a joint. Conventional wisdom has long held that water filtration makes for a cleaner, less harmful consumption experience. But a new...

By 1602, smoking had a bad reputation in England. It stank and caused disease. That year, Swamp Yankees on Cape Cod let the Reverend John Brereton smoke with them. He said their tobacco was way better than London tobacco. It was shoestring tobacco, which wouldn't work in a cheap clay pipe. To make good pipes, Yankees imported stone from mines in Ohio and Minnesota.
In 1964, the US Surgeon General reported that cigarettes shortened lives. He also reported that pipe smokers lived longer than those who had never smoked. Danish research with a smoking machine showed why. Health damage comes from partial combustion of volatile chemicals in tobacco. Their machine picked up lots from cigarettes, none from a pipe.
They found that heat in the pipe bowl vaporized volatiles so that the machine could draw them off before the flame front arrived. That left charcoal to support combustion.
It doesn’t work that well for a human smoker because drawing from a bowl that hot would scald a smoker’s mouth. The European clay pipe was originally to smoke petals that didn’t require high temperatures. However, in King James’ time, some Englishmen were smoking shoestring tobacco, which grows anywhere. He outlawed pipes not made to his specifications. The flue of a flower pipe was 3.6mm in diameter. Monarchs kept reducing the specified diameter. By the time of the American Revolution, it was only 1.6mm. The cooling capacity of a pipe stem depends on the volume of the flue. For a given length, a clay pipe stem now had only 20% of the cooling of a flower pipe. Less cooling meant the bowl had to smolder at a cooler temperature, producing little flavor and lots of pollution. Pipe smoking became so unpopular that US senators chewed and spat, instead.
Yankee pipe bowls were too hot to touch while smoking but could be held by long stems made of reeds or pithy wood. Stem bores were large for good cooling. The bowls could be thrown into the coals of a fire for cleaning.
My pipe, from about 1970, is bakelite with a bowl liner of pyrolytic graphite (developed for missile nose cones). Given enough days to dry between smokes, a briar pipe could partly compensate for the lack of cooling by absorbing moisture (latent heat). The bakelite pipe was unpopular because it wouldn't absorb moisture. Cleaning could easily damage the soft graphite liner, so caking got thick.
I added a length of 5/8" silicone heater hose between stem and mouthpiece. It cools 100 times better than a similar length of conventional pipe stem. I can run the bowl hot enough for clean distillation. The bowl gets too hot to touch, but the hose is a safe handle. The only condensate in the hose is a nice-smelling amber liquid: no tars. With a modern no-scratch scrub cloth, I can clean the bowl with soap and water. Not absorbing water, it's immediately ready to use.
