To make very good E-juice you do not need scale, syringe,funel or calculator. The only thing you need is baby feed bottle like this:
Wide opening is easy to pour ingredients in. To make math easy make 100 ml batch. If you want 70VG/30PG start with pouring your vg till it reach 70ml line. Next add PG based nicotine ...if you like 5 mg pour it till it reach half way between 70 - 80 line. Next add PG based flavors (every 1% equals 1ml)... if you added 15% (15ml) of flavor you reached 90ml line... the rest (10ml) fill with pg. YOU reached 100ml of your batch. Close the bottle shake it and you are done. Nothing to wash...after a day or two fill your regular e-juice bottle and enjoy.
