Different Types of Bongs and Their Benefits Explained
This produces a much cooler, much smoother smoke than the straight-tube, beaker, or round-base bong can provide. Because of the complexity, multi-chamber bongs are more difficult to build. That makes them more expensive than the simpler builds on this list. Multi-chamber bongs are also harder to clean. 6.

Key Concepts. A metal is a lattice of positive metal 'ions' in a 'sea' of delocalised electrons. Metallic bonding refers to the interaction between the delocalised electrons and the metal nuclei. The physical properties of metals are the result of the delocalisation of the electrons involved in metallic bonding.
