Lacrymo

Séquencer le déclenchement de diffuseurs de fumée cachés dans des capsules de bombe lacrymogene trouvés dans la rue après des manifestations.

Afin de pouvoir déclencher successivement des fumée provenant de capsule de bombe lacrymogene. Fumée produite avec PROPYLENE GLYCOL (e-cigarette) + huile essentielle menthe poivrée pour l'ambiance piquante.
