For example, build a summer shower made of glass bottles. Naturally, for starters, you will need the foundation, since the bottles are much lighter than bricks, then the foundation can be made less. If the foundation is ready, then you can start. On average, for the construction of one square meter of wall, you will need about two hundred bottles and 100 liters of solution. The container must be laid, like a brick, only periodically stop due to a floating solution, because the bottle is not brick and does not absorb moisture.
