So... ive seen pictures of bongs that people have made from chemistry equipment before, and they all look pretty sweet. Being interested in science, i decided that id like to make one myself. That's where you guys come in. So far i've found a 1 L boiling flask Aliexpress.com : Buy 1000ml (1L) 2 neck (two neck) flat bottom boiling flask, heavy wall (Pyrex glass meterial) from Reliable flat bottom flask suppliers on Beijing Getty Laboratory Glassware Co.,Ltd. to use for a base, and a straight tube to use for the stem. Aliexpress.com : Buy Straight drying glass tube adapter (Laboratory Glass) (lab suppies) from Reliable drying tube suppliers on Beijing Getty Laboratory Glassware Co.,Ltd. my questions are: will these items be good enough, and make a large enough bong, and should i attempt to use a piece of scientific equipment as a bowl and downstem, or should i just go to a headshop? any other comments or advice are welcomed and appreciated, and if anyone has any scientific glass they want to show off, lets see it.
