Test Your Meth and Proper Use of a Bubble ... Medium
Apr 21, 2016· Using the bubble: Meth has a melting point of 175 °C and a boiling point of 215 °C. Once you hit the boiling point the meth will start to over cook. Rolling the bubble helps prevent this from happen as the glass on the sides are cooler then where the flame is, thus helping slowing down the heating process.
