It's also sort of a bad idea to normalize drinking out of laboratory glassware. Granted your home is different from a real lab, but lab workers have died drinking something they thought was water.
In my dad's lab in the 1970s, they used to make coffee in a large Erlenmeyer flask and filter it under vaccuum with a Buchner funnel. The safety director eventually banned it and made them buy a Mr. Coffee.
I wonder how many undergrads will disassemble their bongs made from spare bits of chemistry glassware after reading your warning about drinking from lab equipment.
