Inverted Bowl is quite new concept comprising of two bowls. In the bottom bowl we put the coals and on the top Inverted bowl we load the shisha tobacco.

1. Pros and Cons

+ There is less ash reaching the shisha tobacco.
+ Easier to handle the charcoals.
+ Safer regarding the risk of fire from dropped charcoal
+ Won’t break when dropped
+ Easy heat management as you can increase or reduce the heat going to the tobacco by adjusting the distance of the coal bowl

- Tobacco juices dripping through the foil holes and on the charcoals (especially the extra juicy tobacco)

- Overall good heat management but it is still possible burn the tobacco if it is overheated
