Self made bong made from the bottom half a 5L bottle filled with
water, as well as the top half of a 1.5L/2L bottle. Common in Eastern European countries, such as Russia, Belarus, Ukraine, Armenia, Georgia etc. It is normally used for smoking
marijuana, which is unfortunately only legal in Georgia among the above mentioned. “Vodnik” is another name for this apparatus. Latter is derived from the Russian “voda” (
water).
