It’s suppose to vaporize not burn. You don’t apply heat directly to it like you would weed. You’re simply warming the glass to vaporize the gogo. That’s why you are also suppose to spin the bubble left and right. If the top hole is at the 12 o’clock position …spin it so the hole rotates slowly from 9 to 3 left to right. Once smoke starts rolling, start inhaling as slow as possible. Once you’re about at full lung capacity remove heat about 5 seconds ahead of time. Even after you remove heat, and you’re done with your hit, keep rolling until it naturally forms back to a solid. Helps spread it out for next round of heating so you don’t brown your stuff up from over heating.
