Demonstration is usually easy to lose control, and escalated to chaos. The tear gas bombs are commonly used in the situation, which can make people tear and cough violently and finally incapacitated.
We designed the “No-tear Gas Bottle”, which contains hypnotic sedative gas. Its shape resembles a drinking bottle. Instead of throwing, agent who mingles with the crowd brings and lays it in the crowd, then leaves the crowd.When people are paying close attention on the protest, the bottle can be barely visible from the crowd. It can be controlled remotely or automatically, slowly releasing the gas as the crowd moves along.
